Detailsinfo

A vulnerability was found in Nlnet Labs Net Dns up to 0.x. It has been classified as critical. Affected is the function net::dns. The manipulation with an unknown input leads to a authentication spoofing vulnerability. CWE is classifying the issue as CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. This is going to have an impact on integrity. CVE summarizes:

Header.pm in Net::DNS before 0.60, a Perl module, (1) generates predictable sequence IDs with a fixed increment and (2) can use the same starting ID for all child processes of a forking server, which allows remote attackers to spoof DNS responses, as originally reported for qpsmtp and spamassassin.

The bug was discovered 06/20/2007. The weakness was released 06/27/2007 as Bug 245458 as confirmed bug report (Bugzilla). The advisory is available at bugzilla.redhat.com.
