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. This vulnerability exists in driver versions 1.0-8762 and 1.0-8774 and is corrected in 1.0-8776 which is being provided with this update. The packages can be found in the non-free/updates media.
