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

=================

 

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

Package / Vulnerable / Unaffected

Description

===========

 

Samba does not properly check memory boundaries when handling trans,

rans2, and nttrans requests.

 

Impact

A remote attacker could send specially crafted requests to a Samba

daemon, leading to the disclosure of arbitrary memory or to a Denial of

Service.

 

Workaround

There is no known workaround at this time.

 

Resolution
