Description

A flaw was found in GIMP. When processing a specially crafted GIMPressionist preset file, the plug-in does not properly validate vector indices before writing into fixed-size arrays. This can lead to an out-of-bounds write, corrupting memory. An attacker could exploit this by convincing a user to load a malicious preset file, potentially causing a crash or enabling arbitrary code execution.
