Description

Security researcher Gustavo Grieco reported a heap overflow in gdk-pixbuf affecting Linux systems using Gnome. This issue is triggered by the scaling of a malformed bitmap format image and results in a potentially exploitable crash.

This issue only affects Linux systems running Gnome. Windows and OS X operating systems are unaffected.
