Hi,

The following vulnerability was published for gimp.

CVE-2025-10934[0]:
| 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.
