Hi,

The following vulnerability was published for gimp.

CVE-2025-2760[0]:
| GIMP XWD 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 XWD 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-25082.

Please note that the original fix was incomplete, cf. [2].
