Application crash via stale ICC profile length
Published Aug 27, 2026 · Updated Aug 27, 2026
Out-of-bounds write in gdk-pixbuf 2.26.4 and later allows context-dependent attackers to crash applications via a crafted JPEG image. The JPEG ICC parser frees a partially assembled profile after an error but retains its stale size, so a later allocation receives an out-of-bounds write. Exploitation requires an application to process a JPEG containing chunked ICC profile markers; the documented consequence is an application crash.
