Red Hat Product Errata RHSA-2004:183 high SHIPPED_LIVE Important: kernel security update 2004-04-22 04:00:00 UTC

Description Mark J. Cox 2004-04-05 12:04:38 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.

Comment 1 Ernie Petrides 2004-04-14 22:36:07 UTC
A fix for this problem has just now been committed to the
Taroon U2 kernel patch pool in kernel version 2.4.21-14.EL.

Comment 2 Mark J. Cox 2004-04-15 20:28:47 UTC
Removing embargo

Comment 3 Mark J. Cox 2004-04-21 18:47:09 UTC
