arbitrary code as root on the server.

Embargoed.  No date for public notification set; CVE applied for.

to 4.1.0.  Errata in progress.

CAN-2004-0083, embargo lifts on Feb11

Comment 4 Mark J. Cox 2004-02-12 13:10:48 UTC

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.
