Synopsis
========

Multiple flaws exist in the Samba suite of programs, the
most serious
of which could result in the execution of arbitrary code.

Background
==========

Samba is a suite of SMB and CIFS client/server programs for
UNIX.

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

   
------------------------------------------------------------
-------
     Package       /  Vulnerable  /                        
Unaffected
   
------------------------------------------------------------
-------
  1  net-fs/samba      < 3.0.24                          
   >= 3.0.24

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

A format string vulnerability exists in the VFS module when
handling
AFS file systems and an infinite loop has been discovered
when handling
file rename operations.

Impact
======

A user with permission to write to a shared AFS file system
may be able
to compromise the smbd process and execute arbitrary code
with the
permissions of the daemon. The infinite loop could be abused
to consume
excessive resources on the smbd host, denying service to
legitimate
users.

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-3.0.24"
