Buffer overflow in Red Hat Enterprise Linux 6
CVE-2026-90947
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.
