CVE-2026-40917 is a medium severity vulnerability in GIMP on Red Hat Enterprise Linux 6 involving a heap buffer over-read in the icns_slurp() function when processing maliciously crafted ICNS image files. This flaw can cause application crashes or potentially leak information. There is no explicit vendor advisory statement about a patch or mitigation in the provided data.
AI Analysis
Technical Summary
This vulnerability is a heap buffer over-read in the icns_slurp() function of GIMP on Red Hat Enterprise Linux 6. It occurs when processing specially crafted ICNS image files, potentially leading to application crashes or information disclosure. The CVSS 3.1 score is 5.0, indicating medium severity with local attack vector, low complexity, requiring low privileges and user interaction, and impacting availability but not confidentiality or integrity. The vendor advisory link is provided but does not explicitly confirm patch availability or remediation status.
Potential Impact
An attacker who can supply a malicious ICNS image file to a system running GIMP on Red Hat Enterprise Linux 6 may cause the application to crash or potentially disclose information due to a heap buffer over-read. The impact is limited to denial of service or information disclosure without elevation of privileges or code execution. There are no known exploits in the wild as per the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-40917 for current remediation guidance. Until an official fix is available, avoid processing untrusted ICNS image files with GIMP on affected systems.
