Red Hat Security Advisory: gimp security update
Multiple security vulnerabilities have been identified in GIMP, the GNU Image Manipulation Program, affecting its image loading plugins. These include a heap-buffer-overflow in the APNG loader when the fcTL width exceeds the IHDR width, a heap-based buffer overflow caused by an integer overflow in the file-fits plugin, and an out-of-bounds read in the file-icns plugin that can lead to information disclosure or a crash. Red Hat has issued a security update for GIMP on Red Hat Enterprise Linux 9 to address these issues.
AI Analysis
Technical Summary
This advisory covers three vulnerabilities in GIMP: CVE-2026-42169 is a heap-buffer-overflow in the APNG loader triggered when the fcTL width exceeds the IHDR width in file-png.c. CVE-2026-66758 is an integer overflow in the file-fits plugin that causes a heap-based buffer overflow on crafted FITS images. CVE-2026-66759 is an out-of-bounds read in the file-icns plugin that can cause information disclosure or application crash when processing crafted ICNS images. These vulnerabilities affect GIMP as packaged in Red Hat Enterprise Linux 9 and related variants. Red Hat has released updated packages to fix these issues.
Potential Impact
Successful exploitation of these vulnerabilities could lead to heap-based buffer overflows causing potential application crashes or memory corruption, and out-of-bounds reads that may disclose sensitive information. The issues arise from improper input validation in image file parsing plugins, which could be triggered by opening specially crafted image files. The severity is rated as high by Red Hat Product Security.
Mitigation Recommendations
Red Hat has released updated GIMP packages for Red Hat Enterprise Linux 9 and its variants that address these vulnerabilities. Users should apply the security update as detailed in Red Hat advisory RHSA-2026:50817 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation is specified or required beyond applying the official update.
