CVE-2009-2409
5.1 · MEDIUMOverview
CVE-2009-2409 is a medium-severity vulnerability affecting gnu gnutls. It was published on July 30, 2009 and has a CVSS 2.0 base score of 5.1 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 5.1, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large.
Remediation
Check the references section for vendor advisories and patches from gnu. Update gnutls to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
