Detailsinfo

A vulnerability classified as problematic was found in ISC BIND up to 9.3.2 (Domain Name Software). This vulnerability affects an unknown code block. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. CVE summarizes:

BIND before 9.2.6-P1 and 9.3.x before 9.3.2-P1 allows remote attackers to cause a denial of service (crash) via a flood of recursive queries, which cause an INSIST failure when the response is received after the recursion queue is empty.

The weakness was released 09/05/2006 as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability was named CVE-2006-4096 since 08/14/2006. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 65306 (AIX 5.2 TL 9 / 5.2 TL 10 : bos.net.tcp.client (U808275)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family AIX Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 15052 (ISC BIND Multiple Remote Denial of Service Vulnerabilities).

Upgrading to version 9.2.6-p1 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (28744), Tenable (65306), SecurityFocus (BID 19859†), Secunia (SA21752†) and SecurityTracker (ID 1016794†).
