Scientific Linux Security Update : bind on SL6.x i386/x86_64

Medium Nessus Plugin ID 101256

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Security Fix(es) :

- A flaw was found in the way BIND handled TSIG authentication for dynamic updates. A remote attacker able to communicate with an authoritative BIND server could use this flaw to manipulate the contents of a zone, by forging a valid TSIG or SIG(0) signature for a dynamic update request. (CVE-2017-3143)

- A flaw was found in the way BIND handled TSIG authentication of AXFR requests. A remote attacker, able to communicate with an authoritative BIND server, could use this flaw to view the entire contents of a zone by sending a specially constructed request packet.
(CVE-2017-3142)

Bug Fix(es) :

- ICANN is planning to perform a Root Zone DNSSEC Key Signing Key (KSK) rollover during October 2017.
Maintaining an up-to-date KSK, by adding the new root zone KSK, is essential for ensuring that validating DNS resolvers continue to function following the rollover.

Solution

Update the affected packages.
