CAN-2004-0109 kernel iso9660 buffer overflow
Last modified: 2013-03-06 00:56:42 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.
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
