Hash: SHA256
Package : pdns
Version : 3.1-4.1+deb7u3
CVE ID : CVE-2016-2120 CVE-2016-7068 CVE-2016-7072 CVE-2016-7073
CVE-2016-7074
Multiple vulnerabilities have been discovered in pdns, an authoritative
DNS server. The Common Vulnerabilities and Exposures project identifies
the following problems:
CVE-2016-2120
Mathieu Lafon discovered that pdns does not properly validate
records in zones. An authorized user can take advantage of this flaw
to crash server by inserting a specially crafted record in a zone
under their control and then sending a DNS query for that record.
CVE-2016-7068
Florian Heinz and Martin Kluge reported that pdns 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.
CVE-2016-7072
Mongo discovered that the webserver in pdns is susceptible to a
denial-of-service vulnerability. A remote, unauthenticated attacker
to cause a denial of service by opening a large number of f TCP
connections to the web server.
CVE-2016-7073 / CVE-2016-7074
Mongo discovered that pdns does not sufficiently validate TSIG
signatures, allowing an attacker in position of man-in-the-middle to
alter the content of an AXFR.
For Debian 7 "Wheezy", these problems have been fixed in version
3.1-4.1+deb7u3.
We recommend that you upgrade your pdns packages.
