CAN-2004-0109 kernel iso9660 buffer overflow
Last modified: 2007-11-30 17:07:01 EST
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.
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.
RHSA-2003:183 is in progress and currently in QA.
An errata has been issued which should help the problem described in this bug report.
This report is therefore being closed with a resolution of ERRATA. For more information
on the solution and/or where to find the updated files, please follow the link below. You may reopen
this bug report if the solution does not work for you.
