Due to multiple vulnerabilities in imlib, a remote unprivileged user
may be able to execute arbitrary code with the privileges of a local
user when that local user has loaded a bitmap (.bmp) format image file
supplied by an untrusted remote user.

popular Open Source projects such as GNOME 1.x. This interface has
been deprecated in the GNOME 2.x environment.
