- CVEs with nessus.description==The DNS protocol protects against spoofing attacks by requiring an attacker to predict both the DNS transaction ID and UDP source port of a request. In recent years, a number of papers have found problems with DNS implementations which make it easier for an attacker to perform DNS cache-poisoning attacks.
Previous versions of BIND did not use randomized UDP source ports. If an attacker was able to predict the random DNS transaction ID, this could make DNS cache-poisoning attacks easier. In order to provide more resilience, BIND has been updated to use a range of random UDP source ports. (CVE-2008-1447)
Note: This errata also updates SELinux policy to allow BIND to use random UDP source ports.
