Debian DSA-3307-1 : pdns-recursor - security update

high Nessus Plugin ID 84650

Synopsis

The remote Debian host is missing a security-related update.

Description

Toshifumi Sakaguchi discovered that the patch applied to pdns-recursor, a recursive DNS server, fixing CVE-2015-1868, was insufficient in some cases, allowing remote attackers to cause a denial of service (service-affecting CPU spikes and in some cases a crash).

Solution

Upgrade the pdns-recursor packages.

For the stable distribution (jessie), this problem has been fixed in version 3.6.2-2+deb8u2.
