When loading a specially crafted JPEG image containing chunked ICC profile markers, an error during ICC profile parsing can leave stale size metadata after the profile buffer is freed. A subsequent allocation in the same decode can cause an out-of-bounds write, potentially crashing the application. To exploit this flaw, an application using gdk-pixbuf must process the malicious JPEG image.\n\nAffected version >= 2.26.4\n\n## Affected\n\n- `gdk-pixbuf2 (all versions)`\n- `glycin-loaders`\n- `loupe`\n- `snapshot`\n- `gdk-pixbuf2`\n- `gdk-pixbuf2 (all versions)`\n- `gdk-pixbuf2 (all versions)`\n- `gdk-pixbuf2 (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nAvoid opening or automatically indexing untrusted JPEG images with applications linked against a vulnerable gdk-pixbuf version until an updated package is installed.","depth":"sunlit","depthScore":26,"depthScoreParts":{"impact":25.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
