The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2025:15024 advisory.

    The libarchive programming library can create and read several different streaming archive formats,     including GNU tar, cpio, and ISO 9660 CD-ROM images. Libarchive is used notably in the bsdtar utility,     scripting language bindings such as python-libarchive, and several popular desktop file managers.

    Security Fix(es):

    * libarchive: Double free at archive_read_format_rar_seek_data() in archive_read_support_format_rar.c     (CVE-2025-5914)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

The version of AHV installed on the remote host is prior to AHV-11.0. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-11.0 advisory.

  - There exists a vulnerability in SQLite versions before 3.50.2 where the number of aggregate terms could     exceed the number of columns available. This could lead to a memory corruption issue. We recommend     upgrading to version 3.50.2 or above. (CVE-2025-6965)

  - ncurses 6.3 before patch 20220416 has an out-of-bounds read and segmentation violation in convert_strings     in tinfo/read_entry.c in the terminfo library. (CVE-2022-29458)

  - Allows modifying some file metadata (e.g. last modified) with filter=data or file permissions (chmod)     with filter=tar of files outside the extraction directory. You are affected by this vulnerability if     using the tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract()     using the filter= parameter with a value of data or tar. See the tarfile extraction filters     documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more     information. Only Python versions 3.12 or later are affected by these vulnerabilities, earlier versions     don't include the extraction filter feature. Note that for Python 3.14 or later the default value of     filter= changed from no filtering to `data, so if you are relying on this new default behavior then     your usage is also affected. Note that none of these vulnerabilities significantly affect the installation     of source distributions which are tar archives as source distributions already allow arbitrary code     execution during the build process. However when evaluating source distributions it's important to avoid     installing source distributions with suspicious links. (CVE-2024-12718)

  - Allows the extraction filter to be ignored, allowing symlink targets to point outside the destination     directory, and the modification of some file metadata. You are affected by this vulnerability if using the     tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract() using the     filter= parameter with a value of data or tar. See the tarfile extraction filters documentation     https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more information. Note that     for Python 3.14 or later the default value of filter= changed from no filtering to `data, so if you     are relying on this new default behavior then your usage is also affected. Note that none of these     vulnerabilities significantly affect the installation of source distributions which are tar archives as     source distributions already allow arbitrary code execution during the build process. However when     evaluating source distributions it's important to avoid installing source distributions with suspicious     links. (CVE-2025-4138, CVE-2025-4330)

  - When using a TarFile.errorlevel = 0 and extracting with a filter the documented behavior is that any     filtered members would be skipped and not extracted. However the actual behavior of TarFile.errorlevel = 0     in affected versions is that the member would still be extracted and not skipped. (CVE-2025-4435)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

    A vulnerability has been identified in the libarchive library, specifically within the     archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately     lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption,     enabling an attacker to execute arbitrary code or cause a denial-of-service condition.(CVE-2025-5914)

    A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that     can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4     content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially     leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within     applications that process such archives using libarchive.(CVE-2025-5916)

    A vulnerability has been identified in the libarchive library. This flaw can be triggered when file     streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-     bounds read can lead to unintended consequences, including unpredictable program behavior, memory     corruption, or a denial-of-service condition.(CVE-2025-5918)

    A vulnerability has been identified in the libarchive library. This flaw involves an 'off-by-one'     miscalculation when handling prefixes and suffixes for file names. This can lead to a 1-byte write     overflow. While seemingly small, such an overflow can corrupt adjacent memory, leading to unpredictable     program behavior, crashes, or in specific circumstances, could be leveraged as a building block for more     sophisticated exploitation.(CVE-2025-5917)
