Mandrake Linux Security Advisory : xscreensaver (MDKSA-2007:097)

Medium Nessus Plugin ID 25157


The remote Mandrake Linux host is missing one or more security updates.


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.


Update the affected packages.
