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)

Tenable has extracted the preceding description block directly from the EulerOS libarchive security advisory.

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

The version of libarchive installed on the remote host is prior to 3.1.2-14. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2912 advisory.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2025:14135 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.
