GLSA-200812-19 : PowerDNS: Multiple vulnerabilities

This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200812-19
(PowerDNS: Multiple vulnerabilities)

Daniel Drown reported an error when receiving a HINFO CH query
(CVE-2008-5277). Brian J. Dowling of Simplicity Communications
discovered a previously unknown security implication of the PowerDNS
behavior to not respond to certain queries it considers malformed
(CVE-2008-3337).

Impact :

A remote attacker could send specially crafted queries to cause a
Denial of Service. The second vulnerability in itself does not pose a
security risk to PowerDNS Nameserver. However, not answering a query
for an invalid DNS record within a valid domain allows for a larger
spoofing window on third-party nameservers for domains being hosted by
PowerDNS Nameserver itself.

Workaround :

There is no known workaround at this time.

Solution :

All PowerDNS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-dns/pdns-2.9.21.2'

Risk factor :

Medium / CVSS Base Score : 6.4
(CVSS2#AV:N/AC:L/Au:N/C:N/I:P/A:P)
