Amazon Linux 2 : pixman (ALAS-2025-2945)

high Nessus Plugin ID 243251

Language:

Synopsis

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

Description

The version of pixman installed on the remote host is prior to 0.34.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2945 advisory.

In libpixman in Pixman before 0.42.2, there is an out-of-bounds write (aka heap-based buffer overflow) in rasterize_edges_8 due to an integer overflow in pixman_sample_floor_y. (CVE-2022-44638)

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 pixman' to update your system.
