 UNIRAS (UK Government CERT) Briefing - 763/06 dated 20.11.06 time 15:10

 Co-ordination Centre)

Title
=====

Two Mandriva Linux Security Advisories:

1. MDKSA-2006:164-1 - Updated xorg-x11/XFree86 packages fix integer overflow vulnerabilities

2. MDKSA-2006:214 - Updated gv packages fix buffer overflow vulnerability

Detail
======

1.  Local exploitation of an integer overflow vulnerability in the
 'CIDAFM()' function in the X.Org and XFree86 X server could allow an
 attacker to execute arbitrary code with privileges of the X server,
 typically root (CVE-2006-3739).

2.  Stack-based buffer overflow in the ps_gettext function in ps.c for GNU
 gv 3.6.2, and possibly earlier versions, allows user-assisted attackers
 to execute arbitrary code via a PostScript (PS) file with certain
 headers that contain long comments, as demonstrated using the
 DocumentMedia header.
