According to the versions of the python2 packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - An issue was discovered in Python through 2.7.16, 3.x     through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through     3.7.4. The email module wrongly parses email addresses     that contain multiple @ characters. An application that     uses the email module and implements some kind of     checks on the From/To headers of a message could be     tricked into accepting an email address that should be     denied. An attack may be the same as in CVE-2019-11340     however, this CVE applies to Python more     generally.(CVE-2019-16056)

  - http.cookiejar.DefaultPolicy.domain_return_ok in     Lib/http/cookiejar.py in Python before 3.7.3 does not     correctly validate the domain: it can be tricked into     sending existing cookies to the wrong server. An     attacker may abuse this flaw by using a server with a     hostname that has another valid hostname as a suffix     (e.g., pythonicexample.com to steal cookies for     example.com). When a program uses     http.cookiejar.DefaultPolicy and tries to do an HTTP     connection to an attacker-controlled server, existing     cookies can be leaked to the attacker. This affects 2.x     through 2.7.16, 3.x before 3.4.10, 3.5.x before 3.5.7,     3.6.x before 3.6.9, and 3.7.x before     3.7.3.(CVE-2018-20852)

  - The documentation XML-RPC server in Python through     2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has     XSS via the server_title field. This occurs in     Lib/DocXMLRPCServer.py in Python 2.x, and in     Lib/xmlrpc/server.py in Python 3.x. If set_server_title     is called with untrusted input, arbitrary JavaScript     can be delivered to clients that visit the http URL for     this server.(CVE-2019-16935)

  - library/glob.html in the Python 2 and 3 documentation     before 2016 has potentially misleading information     about whether sorting occurs, as demonstrated by     irreproducible cancer-research results. NOTE: the     effects of this documentation cross application     domains, and thus it is likely that security-relevant     code elsewhere is affected. This issue is not a Python     implementation bug, and there are no reports that NMR     researchers were specifically relying on     library/glob.html. In other words, because the older     documentation stated 'finds all the pathnames matching     a specified pattern according to the rules used by the     Unix shell,' one might have incorrectly inferred that     the sorting that occurs in a Unix shell also occurred     for glob.glob. There is a workaround in newer versions     of Willoughby nmr-data_compilation-p2.py and     nmr-data_compilation-p3.py, which call sort()     directly.(CVE-2019-17514)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1132 advisory.

    Python is an interpreted, interactive, object-oriented programming language, which includes modules,     classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to     many system calls and libraries, as well as to various windowing systems. This package provides the     python3 executable: the reference interpreter for the Python language, version 3. The majority of its     standard library is provided in the python3-libs package, which should be installed automatically along     with python3. The remaining parts of the Python standard library are broken out into the python3-tkinter     and python3-test packages.

    Security Fix(es):

    * python: Cookie domain check returns incorrect results (CVE-2018-20852)

    * python: email.utils.parseaddr wrongly parses email addresses (CVE-2019-16056)

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1131 advisory.

  - http.cookiejar.DefaultPolicy.domain_return_ok in Lib/http/cookiejar.py in Python before 3.7.3 does not     correctly validate the domain: it can be tricked into sending existing cookies to the wrong server. An     attacker may abuse this flaw by using a server with a hostname that has another valid hostname as a suffix     (e.g., pythonicexample.com to steal cookies for example.com). When a program uses     http.cookiejar.DefaultPolicy and tries to do an HTTP connection to an attacker-controlled server, existing     cookies can be leaked to the attacker. This affects 2.x through 2.7.16, 3.x before 3.4.10, 3.5.x before     3.5.7, 3.6.x before 3.6.9, and 3.7.x before 3.7.3. (CVE-2018-20852)

  - An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x     through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2020:1605 advisory.

  - The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon     receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover     credentials by sniffing the network. (CVE-2018-18074)

  - urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin     redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the     Authorization header to be exposed to unintended hosts or transmitted in cleartext. (CVE-2018-20060)

  - http.cookiejar.DefaultPolicy.domain_return_ok in Lib/http/cookiejar.py in Python before 3.7.3 does not     correctly validate the domain: it can be tricked into sending existing cookies to the wrong server. An     attacker may abuse this flaw by using a server with a hostname that has another valid hostname as a suffix     (e.g., pythonicexample.com to steal cookies for example.com). When a program uses     http.cookiejar.DefaultPolicy and tries to do an HTTP connection to an attacker-controlled server, existing     cookies can be leaked to the attacker. This affects 2.x through 2.7.16, 3.x before 3.4.10, 3.5.x before     3.5.7, 3.6.x before 3.6.9, and 3.7.x before 3.7.3. (CVE-2018-20852)

  - In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the     request parameter. (CVE-2019-11236)

  - The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA     certificates is different from the OS store of CA certificates, which results in SSL connections     succeeding in situations where a verification failure is the correct outcome. This is related to use of     the ssl_context, ca_certs, or ca_certs_dir argument. (CVE-2019-11324)

  - An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x     through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An     application that uses the email module and implements some kind of checks on the From/To headers of a     message could be tricked into accepting an email address that should be denied. An attack may be the same     as in CVE-2019-11340; however, this CVE applies to Python more generally. (CVE-2019-16056)

  - The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has     XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in     Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary     JavaScript can be delivered to clients that visit the http URL for this server. (CVE-2019-16935)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0080 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-10160:
    A security regression of CVE-2019-9636 was discovered in python since commit     d537ab0ff9767ef024f26246899728f0116b1ec3 affecting versions 2.7, 3.5, 3.6, 3.7 and from v3.8.0a4 through     v3.8.0b1, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts     of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or     other kind of information, it is possible for an attacker to provide specially crafted URLs to make the     application locate host-related information (e.g. cookies, authentication data) and send them to a     different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack     may vary based on the application.

    CVE-2019-16056:
    An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x     through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An     application that uses the email module and implements some kind of checks on the From/To headers of a     message could be tricked into accepting an email address that should be denied. An attack may be the same     as in CVE-2019-11340; however, this CVE applies to Python more generally.

    CVE-2019-16935:
    The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has     XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in     Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary     JavaScript can be delivered to clients that visit the http URL for this server.

    CVE-2019-20907:
    In Lib/tarfile.py in Python through 3.8.3, an attacker is able to craft a TAR archive leading to an     infinite loop when opened by tarfile.open, because _proc_pax lacks header validation.

    CVE-2019-5010:
    An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python     2.7.11 / 3.6.6. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a     denial of service. An attacker can initiate or accept TLS connections using crafted certificates to     trigger this vulnerability.

    CVE-2019-9636:
    Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding     (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials,     cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit,     urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate     cookies or authentication data and send that information to a different host than when parsed correctly.
    This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8,     v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1;
    v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1,     v3.7.8, v3.7.8rc1, v3.7.9.

    CVE-2019-9947:
    An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib in Python 3.x through 3.7.3.
    CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument     to urllib.request.urlopen with \r\n (specifically in the path component of a URL that lacks a ? character)     followed by an HTTP header or a Redis command. This is similar to the CVE-2019-9740 query string issue.
    This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.8, v3.5.8rc1,     v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.4,     v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9.

    CVE-2019-9948:
    urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote     attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a     urllib.urlopen('local_file:///etc/passwd') call.

    CVE-2020-14422:
    Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and     IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application     is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this     attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12;
    v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.

    CVE-2020-26116:
    http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5     allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR     and LF control characters in the first argument of HTTPConnection.request.

    CVE-2020-27619:
    In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content     retrieved via HTTP.

    CVE-2020-8492:
    Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1     allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client     because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking.

    CVE-2021-23336:
    The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before     3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and     urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query     parameters using a semicolon (;), they can cause a difference in the interpretation of the request between     the proxy (running with default configuration) and the server. This can result in malicious requests being     cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and     therefore would not include it in a cache key of an unkeyed parameter.

    CVE-2021-3177:
    Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to     remote code execution in certain Python applications that accept floating-point numbers as untrusted     input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used     unsafely.

    CVE-2021-3733:
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.

The version of AOS installed on the remote host is prior to 5.17.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.17.1 advisory.

  - When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to     Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP     connection. If such connections are available to an attacker, they can be exploited in ways that may be     surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped     with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected     (and recommended in the security guide) that this Connector would be disabled if not required. This     vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the     web application - processing any file in the web application as a JSP Further, if the web application     allowed file upload and stored those files within the web application (or the attacker was able to control     the content of the web application by some other means) then this, along with the ability to process a     file as a JSP, made remote code execution possible. It is important to note that mitigation is only     required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth     approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to     Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP     Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading     to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.
    (CVE-2020-1938)

  - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a     certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)

  - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-     free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where,     the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error     occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by     the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction     mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism     to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that     host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.
    (CVE-2019-19338)

  - The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which     allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.
    (CVE-2015-8035)
