[slackware-security] gdm security update (SSA:2003-300-01)

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.

Vulnerabilities and Exposures (CVE) database:
