Mandriva Linux Security Advisory MDKSA-2007:007
http://www.mandriva.com/security/
_______________________________________________________________________

Package : krb5
Date : January 10, 2007
Affected: 2007.0
_______________________________________________________________________

Problem Description:

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.
