Doc Text:	A flaw was found in GIMP. This heap-based buffer overflow vulnerability in the ICNS file parsing component allows a remote attacker to execute arbitrary code. Exploitation requires user interaction, where the target must open a specially crafted malicious file or visit a malicious page. This issue stems from insufficient validation of user-supplied data length before copying it to a buffer, leading to potential arbitrary code execution in the context of the current process.

Description OSIDB Bzimport 2026-02-20 23:01:47 UTC

GIMP ICNS 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 ICNS 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-28530.
