Description
A vulnerability in GIMP's PlayStation TIM loader causes an integer overflow when calculating the size of the Color Look-Up Table (CLUT). This flaw can be triggered by a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, resulting in a denial of service. The issue affects multiple specific versions of GIMP. The CVSS score is 5.5, indicating a medium severity level.

Technical Analysis
The PlayStation TIM loader in GIMP incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow. This overflow occurs when multiplying two 16-bit unsigned short integers, num_colors and num_cluts, which can exceed the maximum integer limit. An attacker can exploit this by providing a specially crafted PlayStation image file, causing the GIMP plug-in to abort and resulting in a denial of service condition.
Potential Impact
Exploitation of this vulnerability leads to denial of service by causing the GIMP plug-in responsible for handling PlayStation TIM image files to abort unexpectedly. There is no indication of confidentiality or integrity impact. The attack requires user interaction (opening a crafted image file) and local access to the application.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, avoid opening untrusted PlayStation TIM image files in GIMP to prevent triggering the denial of service condition.
