Security researcher Gustavo Grieco reported a heap overflow
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.
