"Updated coolkey packages that fix a security issue and various bugs
are now available for Red Hat Enterprise Linux 5.

This update has been rated as having low security impact by the Red
Hat Security Response Team.

coolkey contains the driver support for the CoolKey and Common Access
Card (CAC) Smart Card products. The CAC is used by the U.S.
Government.

Steve Grubb discovered a flaw in the way coolkey created a temporary
directory. A local attacker could perform a symlink attack and cause
arbitrary files to be overwritten. (CVE-2007-4129)

In addition, the updated packages contain fixes for the following bugs
in the CAC Smart Card support :

* CAC Smart Cards can have from 1 to 3 certificates. The coolkey
driver, however, was not recognizing cards if they had less than 3
certificates.

* logging into a CAC Smart Card token with a new application would
cause other, already authenticated, applications to lose their login
status unless the Smart Card was then removed from the reader and
re-inserted.

All CAC users should upgrade to these updated packages, which resolve
these issues."
