Echo: libarchive: security update to 3.7.4-4+e8

medium Tenable Self-Hosted Container Security Plugin ID 461529

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in libarchive. A NULL pointer dereference vulnerability exists in the ACL parsing logic,
 specifically within the archive_acl_from_text_nl() function. When processing a malformed ACL string (such
 as a bare "d" or "default" tag without subsequent fields), the function fails to perform adequate
 validation before advancing the pointer. An attacker can exploit this by providing a maliciously crafted
 archive, causing an application utilizing the libarchive API (such as bsdtar) to crash, resulting in a
 Denial of Service (DoS). (CVE-2026-5745)

Solution

Update the libarchive library and its related packages to version 3.7.4-4+e8 or later.
