Detailsinfo

A vulnerability, which was classified as problematic, was found in ISC BIND up to 9.4.0a2 (Domain Name Software). This affects the function DSA_verify. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality. The summary by CVE is:

BIND 9.6.0, 9.5.1, 9.5.0, 9.4.3, and earlier does not properly check the return value from the OpenSSL DSA_verify function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.

The bug was discovered 01/07/2009. The weakness was published 01/07/2009 (Website). It is possible to read the advisory at us-cert.gov. This vulnerability is uniquely identified as CVE-2009-0025 since 12/15/2008. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 35445 (openSUSE 10 Security Update : bind (bind-5915)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 119925 (IBM AIX BIND Denial of Service Vulnerability).
