Doc Text:
A heap-based buffer overflow in GIMP’s X Window Dump (XWD) file parser allows an attacker to craft a malicious XWD file (or a web page that triggers opening one) that can overflow a heap buffer during parsing and lead to remote code execution in the context of the GIMP process. The flaw is tracked as CVE-2025-10934 and was disclosed by Trend Micro’s Zero Day Initiative on 29 Oct 2025; GIMP has published a fix.

Description OSIDB Bzimport 2025-10-29 21:01:39 UTC 
GIMP XWD File Parsing Heap-based Buffer 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 XWD files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-27823.
