Ubuntu Security Notice (C) 2007-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Peter Johannes Holzer discovered that the Net::DNS Perl module had
predictable sequence numbers. This could allow remote attackers to
carry out DNS spoofing, leading to possible man-in-the-middle attacks.
(CVE-2007-3377)

Steffen Ullrich discovered that the Net::DNS Perl module did not
correctly detect recursive compressed responses. A remote attacker
could send a specially crafted packet, causing applications using
Net::DNS to crash or monopolize CPU resources, leading to a denial of
service. (CVE-2007-3409).

Solution :

Update the affected libnet-dns-perl package.

Risk factor :

Medium / CVSS Base Score : 4.3
