Description
A flaw was found in GIMP. The PlayStation TIM loader, responsible for handling PlayStation image files, incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow. This occurs when multiplying num_colors and num_cluts, both 16-bit unsigned short integers, resulting in a value exceeding the maximum integer limit. An attacker could exploit this by providing a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, effectively resulting in a denial of service.
