4DescriptionCVE.org
A flaw was found in GIMP. A stack buffer overflow vulnerability in the TIM image loader's 4BPP decoding path allows a local user to cause a Denial of Service (DoS). By opening a specially crafted TIM image file, the application crashes due to an unconditional overflow when writing to a variable-length array.
AnalysisAI
Denial of service in GIMP allows local attackers to crash the application by tricking a user into opening a malicious TIM image file. The vulnerability resides in the TIM image loader's 4BPP decoding path, where an unconditional stack buffer overflow occurs when processing a specially crafted file, with no impact on confidentiality or integrity. No active exploitation or public exploit is known, and a vendor patch is available.
Technical ContextAI
The flaw is in GIMP's built-in handling of the TIM (Timber) image format, specifically in the routine that decodes 4‑bits‑per‑pixel (4BPP) data. During decoding, a fixed‑size stack buffer is written to without proper bounds checking, leading to a classic CWE-787 Out-of-bounds Write. The affected component is GIMP as shipped with Red Hat Enterprise Linux 6, 7, 8, and 9 (CPE strings confirm the distribution channels, though the code is part of the GIMP application itself).
RemediationAI
Apply the vendor‑released patch through Red Hat's standard update channels. Exact fix versions are not stated in the advisory, but upgrading to the latest GIMP packages for your RHEL release will resolve the issue. As a temporary workaround, avoid opening untrusted TIM image files in GIMP, though this only reduces exposure and does not eliminate the underlying bug.
