Amazon Linux 2 : LibRaw (ALAS-2025-2954)

critical Nessus Plugin ID 243426

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 a vulnerability as referenced in the ALAS2-2025-2954 advisory.

In LibRaw before 0.21.4, tag 0x412 processing in phase_one_correct in decoders/load_mfbacks.cpp does not enforce minimum w0 and w1 values, which are used for indexing arrays, and may lead to out of bounds memory access. (CVE-2025-43964)

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 LibRaw' to update your system.
