Synopsis
========

A missing boundary check in Samba might lead to the disclosure of
memory contents.

Background
==========

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

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

-------------------------------------------------------------------

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

Samba does not properly check memory boundaries when handling trans,
rans2, and nttrans requests.

Impact

Service.

Workaround

All Samba users should upgrade to the latest version:

# emerge --sync
