Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
USN-544-1 fixed two vulnerabilities in Samba. Fixes for CVE-2007-5398
are unchanged, but the upstream changes for CVE-2007-4572 introduced a
regression in all releases which caused Linux smbfs mounts to fail.
Additionally, Dapper and Edgy included an incomplete patch which
caused configurations using NetBIOS to fail. A proper fix for these
regressions does not exist at this time, and so the patch addressing
CVE-2007-4572 has been removed. This vulnerability is believed to be
an unexploitable denial of service, but a future update will address
this issue. 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 nmbd did
not properly check the length of netbios packets. When samba
is configured as a WINS server, a remote attacker could send
multiple crafted requests resulting in the execution of
arbitrary code with root privileges. (CVE-2007-5398).
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.
