Synopsis
=======

Samba is vulnerable to a remote denial of service attack due to out of sequence print change notification requests.

Background
=========

Samba is a freely available SMB/CIFS implementation which allows seamless interoperability of file and print services to other SMB/CIFS clients.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-fs/samba < 3.0.6 >= 3.0.6

Description
==========

Due to a bug in the printer_notify_info() function, authorized users could potentially crash the Samba server by sending improperly handled print change notification requests in an invalid order. Windows XP SP2 clients can trigger this behavior by sending a FindNextPrintChangeNotify() request before previously sending a FindFirstPrintChangeNotify() request.

Impact
=====

A remote authorized user could potentially crash a Samba server after issuing these out of sequence requests.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All Samba users should upgrade to the latest version:

# emerge sync

# emerge -pv ">=net-fs/samba-3.0.6"
# emerge ">=net-fs/samba-3.0.6"
