What is CVE-2014-2734?
CVE-2014-2734 is a medium-severity vulnerability in Ruby-Lang Ruby, published on 24 Apr 2014. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The openssl extension in Ruby 2.x does not properly maintain the state of process memory after a file is reopened, which allows remote attackers to spoof signatures within the context of a Ruby script that attempts signature verification after performing a certain sequence of filesystem operations. NOTE: this issue has been disputed by the Ruby OpenSSL team and third parties, who state that the original demonstration PoC contains errors and redundant or unnecessarily-complex code that does not appear to be related to a demonstration of the issue. As of 20140502, CVE is not aware of any public comment by the original researcher
