AI-Generated

A vulnerability exists in GIMP's ICO file loader, where an integer overflow during buffer size calculation can result in a heap-based buffer overflow when processing malicious ICO files containing embedded PNG images. This flaw allows remote attackers to execute arbitrary code or crash the application by tricking users into opening a crafted file. Organizations using GIMP should prioritize patching this vulnerability to mitigate potential exploitation risks.

Original NVD Description

A flaw was found in GIMP's ICO file loader. When processing an ICO file containing an embedded PNG image, an integer overflow can occur during the calculation of the required buffer size. This leads to an undersized buffer being allocated, causing a heap-based buffer overflow when the decoded pixel data is written. A remote attacker could exploit this by crafting a malicious ICO file, which, when opened, could lead to arbitrary code execution or a crash.
