Amazon Linux 2 : libarchive (ALAS-2025-2912)

critical Nessus Plugin ID 241767

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

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.

 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update libarchive' to update your system.
