GLSA 200903-07: Samba: Data disclosure

Severity:normal
Title:Samba: Data disclosure
Date:03/07/2009
Bugs: #247620
ID:200903-07

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 Architecture(s)
net-fs/samba < 3.0.33 >= 3.0.33 All supported architectures

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

All Samba users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.33"
