Red Hat Security Advisory 2017-2533-01
Posted Aug 24, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-2533-01 - The Berkeley Internet Name Domain is an implementation of the Domain Name System protocols. BIND includes a DNS server ; a resolver library ; and tools for verifying that the DNS server is operating correctly. Security Fix: It was found that the lightweight resolver protocol implementation in BIND could enter an infinite recursion and crash when asked to resolve a query name which, when combined with a search list entry, exceeds the maximum allowable length. A remote attacker could use this flaw to crash lwresd or named when using the "lwres" statement in named.conf.

3. Description:

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.

Security Fix(es):

* It was found that the lightweight resolver protocol implementation in
BIND could enter an infinite recursion and crash when asked to resolve a
query name which, when combined with a search list entry, exceeds the
maximum allowable length. A remote attacker could use this flaw to crash
lwresd or named when using the "lwres" statement in named.conf.
(CVE-2016-2775)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing the update, the BIND daemon (named) will be restarted
automatically.

5. Bugs fixed (https://bugzilla.redhat.com/):

1357803 - CVE-2016-2775 bind: Too long query name causes segmentation fault in lwresd
