http://security.gentoo.org/

Severity:	normal
Title:	Samba: Denial of Service vulnerability
Date:	07/25/2006
Bugs:	#139369
ID:	200607-10

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	Architecture(s)
net-fs/samba	< 3.0.22-r3	>= 3.0.22-r3	All supported architectures

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 ">=net-fs/samba-3.0.22-r3"
