Description
A flaw was found in GIMP. An integer overflow occurs in the file-pvr plug-in when calculating memory buffer sizes for image dimensions. By tricking a user into opening or previewing a specially crafted PowerVR (.pvr) file, an attacker can trigger a heap-based buffer overflow, potentially leading to arbitrary code execution or a Denial of Service (DoS) via an application crash.

Impact

A flaw in the GIMP file‑pvr plug‑in allows an attacker to trick a user into opening a malformed PowerVR (.pvr) file, causing an integer overflow when calculating buffer sizes and leading to a heap‑based buffer overflow. The overflow can be leveraged to execute arbitrary code or crash the application, resulting in a denial of service. Once the attacker controls memory, execution of malicious payloads is possible.

Affected Systems

The vulnerability is present on systems running GIMP installed on Red Hat Enterprise Linux versions 6 through 10. The affected component is the GIMP file‑pvr plug‑in, which parses .pvr files and is distributed with the GIMP package available for these operating systems.

Risk and Exploitability

The CVSS score of 7 indicates moderate‑to‑high severity. EPSS information is not available, and the vulnerability is not listed in CISA's KEV catalog, so there is no known active exploitation at the time of this analysis. The attack vector is inferred to be local or social‑engineering, as an attacker must entice a user to open or preview a malicious .pvr file. The potential for arbitrary code execution makes the risk significant for compromised or privileged user accounts.

Remediation

Vendor Workaround

--- CME Mitigation Guidance (2026-10-20) --- Disclaimer: The following mitigation solutions are provided as a courtesy, pending the application of an official patch. This content was generated utilizing AI tools in conjunction with data from https://cmetaxonomy.org. Customers are advised to independently evaluate and test these temporary mitigations within their own infrastructure. The highest-value action is to enforce checked arithmetic and header dimension bounds verification before allocating pixel destination buffers in the file-pvr plug-in: upgrade to the fixed Gimp/Gimp:2.8/Gimp builds, which validate header width and height dimensions against MAX_TWIDDLE_SIZE and use checked multiplication for buffer size calculations, closing all 2 injection vectors (opening a crafted .pvr file in GIMP, thumbnailing or previewing a crafted .pvr file). Until patched, this is a concern on Users and automated indexing or thumbnailing services processing PowerVR (.pvr) files, so Avoid opening untrusted PowerVR (.pvr) texture files in GIMP and disable automated thumbnail generation or file indexer processing for .pvr files. As a compensating measure, Compile with signed integer overflow trapping (-ftrapv or UndefinedBehaviorSanitizer) to abort execution if buffer size arithmetic overflows. These controls limit blast radius and contain exploitation, but they do not fix the underlying integer overflow and heap buffer overflow defect — apply the upstream patch to fully remediate.

OpenCVE Recommended Actions

  • Upgrade GIMP to the latest released version that includes the patch for the file‑pvr overflow.
  • Disable or uninstall the GIMP file‑pvr plug‑in if the application is not required to open PowerVR files.
  • Apply all available Red Hat Enterprise Linux system updates that include the GIMP fix and ensure the system is kept current to avoid re‑exposure.
