ALAS2-2026-4100


Amazon Linux 2 (EOS) Security Advisory: ALAS2-2026-4100
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:
