Doc Text:	A flaw was found in GIMP. Remote attackers can exploit this vulnerability by tricking a user into opening a specially crafted ANI (Animated Cursor) file or visiting a malicious web page. This issue stems from an integer overflow during the parsing of ANI files, caused by insufficient validation of user-supplied data before memory allocation. Successful exploitation could allow an attacker to execute arbitrary code on the affected system with the privileges of the current user.	Story Points:	---

Description OSIDB Bzimport 2026-04-11 01:01:29 UTC

GIMP ANI File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of ANI files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28813.
