CVE-2026-40917: Out-of-bounds Read in Red Hat Red Hat Enterprise Linux 6
A flaw was found in GIMP. This vulnerability, a heap buffer over-read in the `icns_slurp()` function, occurs when processing specially crafted ICNS image files. An attacker could provide a malicious ICNS file, potentially leading to application crashes or information disclosure on systems that process such files.
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 maliciously crafted ICNS image files, potentially leading to application crashes or information disclosure. The CVSS 3.1 score is 5.0 (medium), with attack vector local, low attack complexity, low privileges required, and user interaction needed. Red Hat has published an advisory but has not provided explicit patch or remediation details yet.
Potential Impact
Successful exploitation can cause denial of service via application crashes or may lead to information disclosure on affected systems processing crafted ICNS files. The impact is limited to local users who can supply such files and requires user interaction, reducing the risk scope. There are no known exploits in the wild at this time.
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 opening untrusted ICNS image files with GIMP on affected systems.
