Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

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
