Ubuntu 6.06 LTS / 6.10 : libnet-dns-perl vulnerabilities (USN-483-1)

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 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).

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 libnet-dns-perl package.

Risk factor :

Medium / CVSS Base Score : 4.3
(CVSS2#AV:N/AC:M/Au:N/C:N/I:P/A:N)
