Mandriva Linux Security Advisory - A vulnerability in the NVIDIA Xorg driver was discovered by Derek Abdine who found that it did not correctly verify the size of buffers used to render text glyphs, resulting in a crash of the server when displaying very long strings of text. If a user was tricked into viewing a specially crafted series of glyphs, this flaw could be exploited to run arbitrary code with root privileges.
