Description Jan Lieskovsky 2009-02-18 19:24:49 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2009-0642 to
the following vulnerability:

ext/openssl/ossl_ocsp.c in Ruby 1.8 and 1.9 does not properly check
the return value from the OCSP_basic_verify function, which might
allow remote attackers to successfully present an invalid X.509
certificate, possibly involving a revoked certificate.
