VulniPulse record published
Summary
A flaw was found in GIMP. Processing a specially crafted PVR image file with large dimensions can lead to a denial of service (DoS).
This occurs due to a stack-based buffer overflow and an out-of-bounds read in the PVR image loader, causing the application to crash. Systems that process untrusted PVR image files are affected.
This is a Moderate impact vulnerability. The impact may be limited if the PVR image loader is part of an optional component or plugin not enabled by default.
Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-131.
Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE.
Affected products named by the advisory: Red Hat package: gimp.

Mitigation checklist
- To reduce the risk associated with this vulnerability, avoid processing untrusted PVR image files. Users should exercise caution when opening PVR files from unknown or suspicious sources. If the PVR image loader is part of an application that processes untrusted content, consider running that application in a sandboxed environment to limit potential impact.
