An update of the cmake package has been released.

The version of AOS installed on the remote host is prior to 5.18. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.18 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.

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0078 advisory.

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

    CVE-2019-3822:
    libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The     function creating an outgoing NTLM type-3 header     (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents     based on previously received data. The check that exists to prevent the local buffer from getting     overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from     happening. This output data can grow larger than the local buffer if very large 'nt response' data is     extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large     value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes     from the NTLMv2 type-2 response header.

    CVE-2019-3823:
    libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code     handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and     contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads     beyond the allocated buffer. The read contents will not be returned to the caller.

    CVE-2019-5436:
    A heap buffer overflow in the TFTP receiving code allows for DoS or arbitrary code execution in libcurl     versions 7.19.4 through 7.64.1.

    CVE-2019-5481:
    Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3.

    CVE-2019-5482:
    Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3.

    CVE-2020-8177:
    curl 7.20.0 through 7.70.0 is vulnerable to improper restriction of names for files and other resources     that can lead too overwriting a local file when the -J flag is used.

    CVE-2020-8231:
    Due to use of a dangling pointer, libcurl 7.29.0 through 7.71.1 can use the wrong connection when sending     data.

    CVE-2020-8284:
    A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to     a given IP address and port, and this way potentially make curl extract information about services that     are otherwise private and not disclosed, for example doing port scanning and service banner extractions.

    CVE-2020-8285:
    curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue     in FTP wildcard match parsing.

    CVE-2020-8286:
    curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to     insufficient verification of the OCSP response.

    CVE-2021-22946:
    A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an     IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL`     or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly     crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations
    **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear     text over the network.

    CVE-2021-22947:
    When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to     upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches.
    curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using     and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw,     it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS     traffic from the legitimate server and trick curl into sending data back to the user thinking the     attacker's injected data comes from the TLS-protected server.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.
