CVE-2026-4151: GIMP ANI File Parsing Integer Overflow Remote Code Execution Vulnerability

GIMP ANI File Parsing Integer 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 ANI files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28813.

Security readout for executives and security teams

Plain-English summary

CVE-2026-4151 is a high-severity GIMP flaw where a malicious ANI file can make GIMP allocate memory incorrectly and potentially run attacker-controlled code. Exploitation requires user interaction, such as opening a malicious file or visiting a malicious page that triggers file handling.

Executive priority

Prioritize patching managed workstations that use GIMP or process third-party visual assets. The risk is meaningful because code execution is possible, but urgency is below emergency level absent active exploitation evidence.

Technical view

The flaw is an integer overflow in GIMP ANI parsing caused by insufficient validation before buffer allocation. ZDI describes possible arbitrary code execution in the current process. The source bundle identifies GIMP 3.0.8 as affected and links a GNOME commit plus Red Hat advisories.

Likely exposure

Exposure is most likely on workstations or image-processing environments running GIMP 3.0.8, especially where users open externally supplied files. Enterprise Linux packages may be relevant where Red Hat advisories apply.

Exploitation context

The bundle does not cite CISA KEV listing or confirmed active exploitation. Practical exploitation requires convincing a user to open a malicious ANI file or visit a malicious page, so phishing and content-sharing workflows are the main concern.

Researcher notes

Evidence supports CWE-190 integer overflow during ANI parsing before buffer allocation. The bundle does not provide exploit details, fixed release naming, or active exploitation confirmation. Treat the GNOME commit and vendor advisories as primary remediation references.

Mitigation direction

  • Apply GIMP or operating-system vendor updates as directed by official advisories.
  • For Red Hat environments, review RHSA-2026:16484 and RHSA-2026:19362 applicability.
  • Reduce handling of untrusted ANI files until patched.
  • Warn users not to open unexpected image or cursor files from unknown sources.
  • Monitor vendor guidance for fixed-version details not present in the bundle.

Validation and detection

  • Inventory systems with GIMP installed and identify version 3.0.8 exposure.
  • Check package status against GIMP and Red Hat advisory guidance.
  • Confirm endpoint controls flag or quarantine suspicious ANI attachments where possible.
  • Review workflows that ingest externally supplied image, cursor, or design assets.
  • Document whether GIMP is reachable only through trusted-user desktop workflows.
