Amazon Linux 2 : socat, --advisory ALAS2-2026-3303 (ALAS-2026-3303)

critical Nessus Plugin ID 316913

Synopsis

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

Description

The version of socat installed on the remote host is prior to 1.7.3.2-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3303 advisory.

readline.sh in socat through 1.8.0.1 relies on the /tmp/$USER/stderr2 file. (CVE-2024-54661)

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 socat' or or 'yum update --advisory ALAS2-2026-3303' to update your system.
