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.
