Doc Text:
A flaw was found in GIMP. A remote attacker can exploit this out-of-bounds write vulnerability by tricking a user into opening a specially crafted XWD (X Window Dump) file. This issue occurs due to improper validation of user-supplied data during XWD file parsing, leading to a write past the end of an allocated buffer. Successful exploitation could allow the attacker to execute arbitrary code in the context of the current process.

Description OSIDB Bzimport 2026-02-20 23:02:18 UTC 
GIMP XWD File Parsing Out-Of-Bounds Write 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 XWD files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28591.
