The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:1875 advisory.

    The less utility is a text file browser that resembles more, but allows     users to move backwards in the file as well as forwards. Since less does not     read the entire input file at startup, it also starts more quickly than ordinary     text editors.

    Security Fix(es):

    * less: missing quoting of shell metacharacters in LESSCLOSE handling     (CVE-2022-48624)

According to the versions of the less package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE.(CVE-2022-48624)

    less through 653 allows OS command execution via a newline character in the name of a file, because     quoting is mishandled in filename.c. Exploitation typically requires use with attacker-controlled file     names, such as the files extracted from an untrusted archive. Exploitation also requires the LESSOPEN     environment variable, but this is set by default in many common cases.(CVE-2024-32487)

The version of AOS installed on the remote host is prior to 6.8.0.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.8.0.5 advisory.

  - An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might     erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the     `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request     which used that callback. This flaw may surprise the application and cause it to misbehave and either send     off the wrong data or use memory after free or similar in the second transfer. The problem exists in the     logic for a reused handle when it is (expected to be) changed from a PUT to a POST. (CVE-2023-28322)

  - This flaw allows an attacker to insert cookies at will into a running program using libcurl, if the     specific series of conditions are met. libcurl performs transfers. In its API, an application creates     easy handles that are the individual handles for single transfers. libcurl provides a function call that     duplicates en easy handle called     [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies     enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the     actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned     version of the handle would instead store the file name as `none` (using the four ASCII letters, no     quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from     would then inadvertently load cookies from a file named `none` - if such a file exists and is readable in     the current directory of the program using libcurl. And if using the correct file format of course.
    (CVE-2023-38546)

  - CVE-2023-38546 is a cookie injection vulnerability in the curl_easy_duphandle(), a function in libcurl     that duplicates easy handles.  When duplicating an easy handle, if cookies are enabled, the duplicated     easy handle will not duplicate the cookies themselves, but would instead set the filename to none.'     Therefore, when the duplicated easy handle is subsequently used, if a source was not set for the cookies,     libcurl would attempt to load them from the file named none' on the disk.  This vulnerability is rated     low, as the various conditions required for exploitation are unlikely.  (CVE-2023-38546)

  - This flaw allows a malicious HTTP server to set super cookies in curl that are then passed back to more     origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get     sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in     curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a     cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though     `co.uk` is listed as a PSL domain. (CVE-2023-46218)

  - libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are     required in the case of a large token for which multiple buffer fills are needed. (CVE-2023-52425)

  - This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to     pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting     done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected     to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due     to this bug, the local variable that means let the host resolve the name could get the wrong value     during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target     buffer instead of copying just the resolved address there. The target buffer being a heap based buffer,     and the host name coming from the URL that curl has been told to operate with. (CVE-2023-38545)

  - CVE-2023-38545 is a heap-based buffer overflow vulnerability in the SOCKS5 proxy handshake in libcurl and     curl.  When curl is given a hostname to pass along to a SOCKS5 proxy that is greater than 255 bytes in     length, it will switch to local name resolution in order to resolve the address before passing it on to     the SOCKS5 proxy. However, due to a bug introduced in 2020, this local name resolution could fail due to a     slow SOCKS5 handshake, causing curl to pass on the hostname greater than 255 bytes in length into the     target buffer, leading to a heap overflow.  The advisory for CVE-2023-38545 gives an example exploitation     scenario of a malicious HTTPS server redirecting to a specially crafted URL. While it might seem that an     attacker would need to influence the slowness of the SOCKS5 handshake, the advisory states that server     latency is likely slow enough to trigger this bug. (CVE-2023-38545)

(CVE-2024-21094)

  - A flaw was found in Buildah (and subsequently Podman Build) which allows containers to mount arbitrary     locations on the host filesystem into build containers. A malicious Containerfile can use a dummy image     with a symbolic link to the root filesystem as a mount source and cause the mount operation to mount the     host root filesystem inside the RUN step. The commands inside the RUN step will then have read-write     access to the host filesystem, allowing for full container escape at build time. (CVE-2024-1753)

  - A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits     deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such     as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size     from 513 to 512 bits, exposing a potential timing side-channel. (CVE-2024-28834)

  - The DNS message parsing code in `named` includes a section whose computational complexity is overly high.
    It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive     CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative     servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through     9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1     through 9.18.21-S1. (CVE-2023-4408)

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote     attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the     KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the     protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG     records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)     allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC     responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an     algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to     it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to     crash an application or overwrite a neighbouring variable. (CVE-2024-2961)
