XScreenSaver 4.10, when using a remote directory service for credentials, does not properly handle the results from the getpwuid function in drivers/lock.c when there is no network connectivity, which causes XScreenSaver to crash and unlock the screen and allows local users to bypass authentication.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
