NewCVE-2026-90947 (opens in a new tab)Amendment
The AlmaLinux security team deemed this advisory irrelevant for AlmaLinux:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pygtk2-doc package and not the pygtk2-doc package as distributed by AlmaLinux.
A flaw was found in GIMP. When processing a specially crafted lighting preset file, the Lighting Effects filter does not properly validate the number of light sources. This can lead to an out-of-bounds write, corrupting memory. An attacker could exploit this by convincing a user to open a malicious preset file, potentially causing a crash or enabling arbitrary code execution.
