Hello Kurt, Steve, vendors, a security flaw was found in the way the OpenSSL extension of the Ruby programming language (of version from the Git trunk repository after 2011-09-01 up to 2011-11-03) generated exponent value to be used for private RSA key generation (the bug caused the exponent for the generated key to be always '1'). A remote attacker could use this flaw to bypass / corrupt integrity of services, depending on strong private RSA keys generation mechanism. Relevant upstream patch: [1] http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=33633 References: [2] https://bugzilla.redhat.com/show_bug.cgi?id=751800 Could you allocate a CVE id for this? Thank you && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
