Description Martin Prpič 2014-12-09 12:33:19 UTC

A flaw was found in the way PowerDNS Recursor resolved certain specially crafted domain names. A remote attacked could use a specially crafted domain name that, when processed by PowerDNS Recursor, would affect the performance of PowerDNS, potentially resulting in a denial of service.

More information can be found in the upstream advisory:

Created pdns-recursor tracking bugs for this issue:

Affects: fedora-all [bug 1172117]
Affects: epel-all [bug 1172118]

Fedora is not affected. We have already the latest stable pdns-recursor 3.6.2 updates for Fedora and Fedora-EPEL.
