Mandriva Linux Security Advisory MDKSA-2007:097
http://www.mandriva.com/security/
_______________________________________________________________________

Package : xscreensaver
Date : May 2, 2007
Affected: 2007.0, 2007.1, Corporate 3.0
_______________________________________________________________________

Problem Description:

A problem with the way xscreensaver verifies user passwords
was discovered by Alex Yamauchi. When a system is using remote
authentication (i.e. LDAP) for logins, a local attacker able to cause
a network outage on the system could cause xscreensaver to crash,
which would unlock the screen.

Updated packages have been patched to correct this issue.
