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

Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 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.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 5.8
(CVSS2#AV:N/AC:M/Au:N/C:N/I:P/A:P)
CVSS Temporal Score : 4.8
(CVSS2#E:F/RL:OF/RC:C)
Public Exploit Available : true
