Detailsinfo

A vulnerability was found in ISC BIND up to 9.9.4 (Domain Name Software) and classified as critical. Affected by this issue is the function query_findclosestnsec3 of the file bin/named/query.c of the component DNS Query Handler. The manipulation with an unknown input leads to a memory corruption vulnerability (NSEC3-Signed Zones). Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is availability. CVE summarizes:

The query_findclosestnsec3 function in query.c in named in ISC BIND 9.6, 9.7, and 9.8 before 9.8.6-P2 and 9.9 before 9.9.4-P2, and 9.6-ESV before 9.6-ESV-R10-P2, allows remote attackers to cause a denial of service (INSIST assertion failure and daemon exit) via a crafted DNS query to an authoritative nameserver that uses the NSEC3 signing feature.

The weakness was shared 01/10/2014 by Jared Mauch as AA-01078 as confirmed advisory (Website). The advisory is shared for download at kb.isc.org. This vulnerability is handled as CVE-2014-0591 since 12/27/2013. The attack may be launched remotely. No form of authentication is required for exploitation.
