CVE: CVE-2009-2409
Component: deprecate MD2 in SSL cert validation (Kaminsky)
Severity: Moderate
Release date: 2009-07-29T00:00:00+00:00

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.
