sol14204: BIND vulnerability CVE-2011-4313 

Security Advisory

Original Publication Date: 02/12/2013

Description

ISC reports that query.c in BIND may allow remote attackers to cause a 
denial-of-service (assertion failure and named exit). The vulnerability uses
unknown vectors related to recursive DNS queries, error logging, and the 
caching of an invalid record by the resolver. The affected versions of BIND are
as follows:

    9.0.x through 9.6.x
    9.4-ESV through 9.4-ESV-R5
    9.6-ESV through 9.6-ESV-R5
    9.7.0 through 9.7.4
    9.8.0 through 9.8.1
    9.9.0a1 through 9.9.0b1

Impact

This issue may cause recursive name servers to crash. 

This issue may affect BIG-IP systems in which BIND is configured as a recursive
name server.

default on these Enterprise Manager systems. These products are only vulnerable
if BIND was manually configured and enabled.

Recommended action

To eliminate this vulnerability, upgrade to a version that is listed in the 
Versions known to be not vulnerable column in the previous table.
