A stack-based buffer overflow in GIMP occurs while parsing APNG files, because user-supplied length data is not validated before it is copied into a stack buffer. An attacker can trigger it if the user opens a malicious file or visits a malicious page. Successful exploitation runs arbitrary code in the current GIMP process. Affected GIMP versions are not stated.
What to do: No fixed version is stated. Apply GIMP's update for CVE-2026-92183 when the vendor publishes it.

Description · NVD
GIMP APNG File Parsing Stack-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 APNG files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29400.
