CVE-2008-3217

Status Candidate

Overview

PowerDNS Recursor before 3.1.6 does not always use the strongest random number generator for source port selection, which makes it easier for remote attack vectors to conduct DNS cache poisoning. NOTE: this is related to incomplete integration of security improvements associated with addressing CVE-2008-1637.

Gentoo Linux Security Advisory 200804-22
Posted Aug 22, 2008

Gentoo Linux Security Advisory [UPDATE] GLSA 200804-22:03 - 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). Versions less than 3.1.6 are affected.
