Synopsis
========

A large number of share connection requests could cause a Denial of
Service within Samba.

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 lt; 3.0.22-r3 gt;= 3.0.22-r3

Description
===========

During an internal audit the Samba team discovered that a flaw in the
way Samba stores share connection requests could lead to a Denial of
Service.

Impact
======

By sending a large amount of share connection requests to a vulnerable
Samba server, an attacker could cause a Denial of Service due to memory
consumption.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Samba users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=net-fs/samba-3.0.22-r3"
