SCA: security update for excon (GHSA-q58g-455p-8vw9)
medium Tenable Cloud Security Plugin ID 423489
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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. (CVE-2019-16779)
