Amazon Linux 2023 : gnupg2, gnupg2-minimal, gnupg2-smime (ALAS2023-2026-1380)

high Nessus Plugin ID 298121

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1380 advisory.

 In GnuPG before 2.4.9, armor_filter in g10/armor.c has two increments of an index variable where one is intended, leading to an out-of-bounds write for crafted input. (For ExtendedLTS, 2.2.51 and later are fixed versions.) (CVE-2025-68973)

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 'dnf update gnupg2 --releasever 2023.10.20260202' or or 'dnf update --advisory ALAS2023-2026-1380 --releasever 2023.10.20260202' to update your system.
