gdm security update

GDM is the GNOME Display Manager, and is commonly used to provide
a graphical login for local users.

Upgraded gdm packages are available for Slackware 9.0, 9.1,
and -current. These fix two vulnerabilities which could allow a local
user to crash or freeze gdm, preventing access to the machine until a
reboot. Sites using gdm should upgrade, especially sites such as
computer labs that use gdm to provide public or semi-public access.

More details about these issues may be found in the Common
Vulnerabilities and Exposures (CVE) database:
