Amazon Linux 2 : LibRaw, --advisory ALAS2-2026-3258 (ALAS-2026-3258)

critical Nessus Plugin ID 311218

Synopsis

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

Description

The version of LibRaw installed on the remote host is prior to 0.19.4-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3258 advisory.

An integer overflow vulnerability exists in the deflate_dng_load_raw functionality of LibRaw. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2026-20884)

A heap-based buffer overflow vulnerability exists in the x3f_load_huffman functionality of LibRaw Commit d20315b. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2026-24660)

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

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

Solution

Run 'yum update LibRaw' or or 'yum update --advisory ALAS2-2026-3258' to update your system.
