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.
AnalysisAI
An out-of-bounds write in GIMP's Lighting Effects filter allows memory corruption when a victim opens a specially crafted lighting preset file, resulting in a crash or potentially arbitrary code execution in the context of the GIMP process. The CVSS vector (AV:L/UI:R) confirms the attack is file-driven and requires a user to open the malicious preset, so no remote unauthenticated path exists; exploitation depends on social engineering. …
