GHSA-237W-6C39-25RH

Vulnerability from github – Published: 2026-08-27 21:31 – Updated: 2026-08-27 21:31

Details

A flaw was found in gdk-pixbuf. 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.

Affected version >= 2.26.4

Severity

4.7 (Medium)
