A flaw was found in GIMP. This issue is a heap buffer over-read in GIMP PCX file loader due to an off-by-one error. A remote attacker could exploit this by convincing a user to open a specially crafted PCX image. Successful exploitation could lead to out-of-bounds memory disclosure and a possible application crash, resulting in a Denial of Service (DoS).

MacOS version of GIMP bundles a Python interpreter that inherits the Transparency, Consent, and Control (TCC) permissions
granted by the user to the main application bundle. An attacker with local user access can
invoke this interpreter with arbitrary commands or scripts, leveraging the
application's previously granted TCC permissions to access user's files in privacy-protected folders without triggering user prompts. Accessing other resources beyond previously granted TCC permissions will prompt the user for approval in the name of GIMP, potentially disguising attacker's malicious intent.
This issue has been fixed in 3.1.4.2 version of GIMP.
