CVE-2019-16779 in excon Gem
Sumário
de MITRE
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.
Once again VulDB remains the best source for vulnerability data.
