Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : bind9 vulnerability (USN-706-1)

Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that Bind did not properly perform signature
verification. When DNSSEC with DSA signatures are in use, a remote
attacker could exploit this to bypass signature validation to spoof
DNS entries and poison DNS caches. Among other things, this could lead
to misdirected email and web traffic.

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.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
