Bug#475154: gnome-screensaver: CVE-2008-1683 unlocks session if it fails to get user attributes via getpwnam()

[Nico Golde]

Package: gnome-screensaver
Severity: grave
Tags: security

Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for gnome-screensaver.


CVE-2008-1683[0]:
| xscreensaver on Fedora 8, when an NIS authentication server is
| enabled, exits if this server is unavailable as the xscreensaver
| process is starting, which allows physically proximate attackers to
| gain access to a workstation session for which locking was intended, a
| related issue to CVE-2007-1859.

The CVE text is somehow wrong I think. Reading the redhat 
bugzilla in the references this is a gnome-screensaver issue 
and was not reproducible in xscreensaver.

Patch is on:
https://bugzilla.redhat.com/attachment.cgi?id=297817

If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
