GLSA-200804-22 : PowerDNS Recursor: DNS Cache Poisoning

medium Nessus Plugin ID 32015

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-200804-22 (PowerDNS Recursor: DNS Cache Poisoning)

 Amit Klein of Trusteer reported that insufficient randomness is used to calculate the TRXID values and the UDP source port numbers (CVE-2008-1637). Thomas Biege of SUSE pointed out that a prior fix to resolve this issue was incomplete, as it did not always enable the stronger random number generator for source port selection (CVE-2008-3217).
 Impact :

 A remote attacker could send malicious answers to insert arbitrary DNS data into the cache. These attacks would in turn help an attacker to perform man-in-the-middle and site impersonation attacks.
 Workaround :

 There is no known workaround at this time.

Solution

All PowerDNS Recursor users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/pdns-recursor-3.1.6'
