CVE-2026-80101— Gimp: multiple heap out-of-bounds reads in xwd loader from unrelated width and bytes-per-line validation

Quick assessment

Affected
GNOME GIMP
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
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组织开源的一款专业图像编辑软件。 GIMP存在缓冲区错误漏洞，该漏洞源于在处理特制的XWD图像文件时，独立验证图像宽度和每行字节数参数而未确保组合值与分配缓冲区大小一致，导致边界检查不当，造成堆越界读取，可能导致应用程序崩溃，造成拒绝服务，或导致堆内存内容有限泄露到生成的图像中。

Vulnerability Title
Gimp: multiple heap out-of-bounds reads in xwd loader from unrelated width and bytes-per-line validation
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the file-xwd plugin in GIMP. When processing a specially crafted XWD image file, the plugin validates the image width and bytes-per-line parameters independently rather than ensuring their combined values are consistent with the allocated buffer size. This incorrect validation leads to improper bounds checking, causing a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents into the produced image.
