Package : pdns-recursor
Version : 3.3-3+deb7u2
CVE ID : CVE-2016-9139
Florian Heinz and Martin Kluge reported that pdns-recursor, a recursive
DNS server, parses all records present in a query regardless of whether
they are needed or even legitimate, allowing a remote, unauthenticated
attacker to cause an abnormal CPU usage load on the pdns server,
resulting in a partial denial of service if the system becomes
overloaded.
For Debian 7 "Wheezy", these problems have been fixed in version
3.3-3+deb7u2.
We recommend that you upgrade your pdns-recursor packages.
Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
