Derek Abdine discovered that the NVIDIA Xorg driver did not correctly verify the size of buffers used to render text glyphs. When displaying very long strings of text, the Xorg server would crash. If a user were tricked into viewing a specially crafted series of glyphs, this flaw could be exploited to run arbitrary code with root privileges.

If a user were tricked into viewing or processing a specially crafted image with an application that uses imlib2, the flaws could be exploited to execute arbitrary code with the user's privileges.
