This script is Copyright (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Multiple vulnerabilities has been discovered and corrected in samba :

The chain_reply function in process.c in smbd in Samba before 3.4.8
and 3.5.x before 3.5.2 allows remote attackers to cause a denial of
service (NULL pointer dereference and process crash) via a Negotiate
Protocol request with a certain 0x0003 field value followed by a
Session Setup AndX request with a certain 0x8003 field value
(CVE-2010-1635).

The reply_sesssetup_and_X_spnego function in sesssetup.c in smbd in
Samba before 3.4.8 and 3.5.x before 3.5.2 allows remote attackers to
trigger an out-of-bounds read, and cause a denial of service (process
crash), via a \xff\xff security blob length in a Session Setup AndX
request (CVE-2010-1642).

The updated packages provides samba 3.4.8 which is not vulnerable to
these issues.
