Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

GIMP是GIMP组织开源的一款开源的位图图像编辑器。 GIMP存在数字错误漏洞，该漏洞源于PlayStation TIM加载器在处理PlayStation图像文件时，因整数溢出错误计算Color Look-Up Table（CLUT）的大小，导致num_colors和num_cluts相乘结果超出最大整数限制，攻击者可通过提供特制图像文件导致GIMP插件中止，有效造成拒绝服务。

Vulnerability Title
Gimp: gimp: denial of service via integer overflow in playstation tim loader
Source: CVE Program / CVE List V5
Vulnerability 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.
