 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.
