Subject: [USN-29-1] samba vulnerability

===========================================================
Ubuntu Security Notice USN-29-1		  November 18, 2004
samba vulnerability
CAN-2004-0882
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

samba

The problem can be corrected by upgrading the affected package to
version 3.0.7-1ubuntu6.2.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

During an audit of the Samba 3.x code base Stefan Esser discovered a
Unicode file name buffer overflow within the handling of
TRANSACT2_QFILEPATHINFO replies. A malicious samba user with write
access to a share could exploit this by creating specially crafted
path names (files with very long names containing Unicode characters)
that would overflow an internal buffer and could lead to remote
execution of arbitrary code with the privileges of the samba server.

Since the samba server usually (by default) runs as root, this flaw
can lead to privilege escalation and unbounded system compromise.
