Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2008-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
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).
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected packages.
