Ubuntu 6.06 LTS / 7.04 / 7.10 / 8.04 LTS : samba regression (USN-617-2)

Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2008-2013 Tenable Network Security, Inc.

Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

USN-617-1 fixed vulnerabilities in Samba. The upstream patch
introduced a regression where under certain circumstances accessing
large files might cause the client to report an invalid packet length
error. This update fixes the problem.

We apologize for the inconvenience.

Samba developers discovered that nmbd could be made to overrun a
buffer during the processing of GETDC logon server requests. When
samba is configured as a Primary or Backup Domain Controller, a remote
attacker could send malicious logon requests and possibly cause a
denial of service. (CVE-2007-4572)

Alin Rad Pop of Secunia Research discovered that Samba did
not properly perform bounds checking when parsing SMB
replies. A remote attacker could send crafted SMB packets
and execute arbitrary code. (CVE-2008-1105).

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 9.3
