Vulnerability Title
Gdk-pixbuf: gdk-pixbuf: invalid write in jpeg icc profile parser on error recovery
Source: CVE Program / CVE List V5
Vulnerability Description
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
