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