GIMP Fails to Safely Open Malicious XWD Files, Allowing Code Execution

Summary

GIMP's XWD file parser is not secure, allowing hackers to execute code on your computer if you open a specially crafted XWD file. To stay safe, avoid opening XWD files from unknown sources and ensure you have the latest version of GIMP installed. If you're concerned, consider replacing XWD support with a safer alternative.

What to do

Update debian gimp to version 2.10.22-4+deb11u6.
Update debian gimp to version 2.10.34-1+deb12u9.
Update debian gimp to version 3.0.4-3+deb13u7.
Update debian gimp to version 3.2.0~RC3-1.

Original description

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-28265.
