Unspecified vulnerability in PowerDNS Recursor (aka pdns_recursor) 3.6.x before 3.6.1 allows remote attackers to cause a denial of service (crash) via an unknown sequence of malformed packets.

- PowerDNS Recursor Security Release 3.6.1

    - CVE-2014-3614

Issue: A specific sequence of packets can crash PowerDNS Recursor 3.6.0 remotely (CVE-2014-3614) Affected: All deployments of PowerDNS Recursor 3.6.0

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its self-reported version number, the version of the PowerDNS Recursor service listening on the remote host is version 3.6.0. It is, therefore, affected by a denial of service vulnerability due to improper handling of malformed packet sequences. An unauthenticated, remote attacker can exploit this to crash the application, resulting in a denial of service condition.

Note that Nessus has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.
Also, Nessus has not checked for the presence of the patch or the workaround.
