Description Mark J. Cox 2004-04-05 12:05:07 UTC 
In Feburary, iDefense notified us of a flaw in the iso9660 filesystem
component of the Linux kernel.  

The Linux kernel performs no length checking on symbolic links stored
on an ISO9660 filesystem, allowing a malformed CD to perform an
arbitrary length overflow in kernel memory. 

In order to exploit this vulnerability, an attacker must be able to
mount a maliciously constructed filesystem (for example by being at
the machine in order to insert a cdrom)

This issue is embargoed until 1400UTC on April 14th 2004.
