ALAS2023-2026-3433


Amazon Linux 2023 Security Advisory: ALAS2023-2026-3433
Advisory Released Date: 2026-11-12
Advisory Updated Date: 2026-11-12
Severity: Medium

Issue Overview:

A flaw was found in gdk-pixbuf. When loading a specially crafted JPEG image containing chunked ICC profile markers, an error during ICC profile parsing can leave stale size metadata after the profile buffer is freed. A subsequent allocation in the same decode can cause an out-of-bounds write, potentially crashing the application. To exploit this flaw, an application using gdk-pixbuf must process the malicious JPEG image.

Affected version >= 2.26.4 (CVE-2026-81893)


Affected Packages:

gdk-pixbuf2


Issue Correction:
Run dnf update gdk-pixbuf2 --releasever 2023.12.20261112 or dnf update --advisory ALAS2023-2026-3433 --releasever 2023.12.20261112 to update your system.
