CVE-2026-4151: GIMP ANI file parsing integer overflow

CVE-2026-4151 · Severity: high · CVSS 7.8 · Published 2026-04-11

GIMP is a popular open-source image editing application. A vulnerability in how it processes animated cursor (ANI) files could allow an attacker to take control of a user's computer if the user is tricked into opening a malicious file or visiting a compromised website. This could lead to the theft of sensitive data or the installation of malware.

Technologies: Gimp, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux AppStream. Vendors: Gimp, Red Hat.

Technical details

An integer overflow vulnerability exists in GIMP's ANI file parsing component due to insufficient validation of user-supplied data. The flaw occurs when the application calculates the size for a buffer allocation, leading to a heap-based buffer overflow. An attacker can exploit this by providing a specially crafted ANI file, which requires the victim to manually open the file or interact with a malicious webpage. Successful exploitation allows for arbitrary code execution within the context of the current process. Patches have been released by GIMP and Red Hat (RHSA-2026:16484, RHSA-2026:19362).
