Out-of-Bounds Heap Read Vulnerability in GIMP Image Loader
CVE-2026-96545

4.4MEDIUM

What is CVE-2026-96545?

A flaw in the TIM image loader of GIMP could lead to an out-of-bounds heap read when processing specially crafted 4bpp TIM images. Specifically, an undersized row buffer is allocated, yet the processing logic attempts to utilize a larger RGBA row size. This discrepancy can lead to the copying of adjacent heap contents into the resulting image, which may not only cause the plugin to crash but also potentially expose sensitive data.
