Comment 1 Mark J. Cox 2004-02-06 05:07:22 EST

CAN-2004-0083, embargo lifts on Feb11

Comment 4 Mark J. Cox 2004-02-12 08:10:48 EST

Subsequently, iDefense found another issue in the same routine with
the same consequences which has been given CVE name CAN-2004-0083.

Additionally David Dawes discovered additional flaws in reading font
files. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0106 to these issues.

That's a typo, the second issue is CAN-2004-0084.
