Vulnerability from variot

In RubyGem excon before 0.71.0, there was a race condition around persistent connections, where a connection which is interrupted (such as by a timeout) would leave data on the socket. Subsequent requests would then read this data, returning content from the previous response. The race condition window appears to be short, and it would be difficult to purposefully exploit this. RubyGem excon Contains an input validation vulnerability.Information may be obtained. RubyGem excon is an HTTP server for Ruby applications.

There are security vulnerabilities in RubyGem excon versions prior to 0.71.0. An attacker could use this vulnerability to leak information

      data: "In RubyGem excon before 0.71.0, there was a race condition around persistent connections, where a connection which is interrupted (such as by a timeout) would leave data on the socket. Subsequent requests would then read this data, returning content from the previous response. The race condition window appears to be short, and it would be difficult to purposefully exploit this. RubyGem excon Contains an input validation vulnerability.Information may be obtained. RubyGem excon is an HTTP server for Ruby applications. \n\r\n\r\nThere are security vulnerabilities in RubyGem excon versions prior to 0.71.0. An attacker could use this vulnerability to leak information",
