Doc Text:
A remote code execution (RCE) vulnerability exists in GIMP due to improper bounds checking during the parsing of ICNS image files. When a user opens a specially crafted ICNS file, it can trigger an out-of-bounds write, allowing attackers to execute arbitrary code within the context of the GIMP process.

Description OSIDB Bzimport 2025-10-29 20:01:51 UTC 
GIMP ICNS 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 ICNS 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-27684.
