A local attacker could perform a symlink attack and cause<br>arbitrary files to be overwritten. (CVE-2007-4129)<br>In addition, the updated packages contain fixes for the following bugs in<br>the CAC Smart Card support:<br><li> CAC Smart Cards can have from 1 to 3 certificates. The coolkey driver,</li> however, was not recognizing cards if they had less than 3 certificates.<br><li> logging into a CAC Smart Card token with a new application would cause</li> other, already authenticated, applications to lose their login status<br>unless the Smart Card was then removed from the reader and re-inserted.<br>All CAC users should upgrade to these updated packages, which resolve these<br>issues.
