Summary
GIMP TIF 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 TIF 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-29403. A flaw was found in GIMP.

Mitigation checklist
- Since this vulnerability requires user interaction with a malicious file, users should exercise caution when opening TIF image files from untrusted sources. To further reduce risk, consider running GIMP within a sandboxed environment, such as a container or Flatpak, to limit the potential impact of a successful exploit.
