7.0High

Published 16 Oct 2026 · NVD status: Received · AI triage by gemini-3.8-flash

7.0High

Attack vector: Local
Complexity: High
Privileges needed: None
User interaction: Required
Impact: Full C/I/A compromise
Weakness: CWE-190

Impact

An attacker can achieve arbitrary code execution or crash the application under the running user's context. This requires tricking a user into opening or previewing a malicious PowerVR (.pvr) file.

Root cause

An integer overflow in the file-pvr plug-in miscalculates buffer sizes for image dimensions, leading to a heap-based buffer overflow.

Affected systems

Versions not listed — check the vendor advisory.

CVSS v3.1 · CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H

Fix & remediation

Update GIMP once patched packages are available from your distribution. As an interim workaround, delete or remove execute permissions on the file-pvr plug-in binary to disable .pvr file handling.

shell

$ sudo chmod 000 /usr/lib/gimp/2.0/plug-ins/file-pvr/file-pvr 2>/dev/null || sudo chmod 000 /usr/lib64/gimp/2.0/plug-ins/file-pvr/file-pvr

AI-suggested. Run it in staging first and check it against the vendor advisory. Why?

NVD 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.
