medium Tenable Cloud Security Plugin ID 463559

Description

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

 - A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-
 read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber (LZSS) window.
 This means the library may attempt to read beyond the allocated memory buffer, which can result in
 unpredictable program behavior, crashes (denial of service), or the disclosure of sensitive information
 from adjacent memory regions. (CVE-2025-5915)

Solution

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