Description
RubyGems version 2.6.12 and earlier is vulnerable to a DNS hijacking vulnerability that allows a MITM attacker to force the RubyGems client to download and install gems from a server that the attacker controls.
A vulnerability was found where rubygems did not sanitize DNS responses when requesting the hostname of the rubygems server for a domain, via a _rubygems._tcp DNS SRV query. An attacker with the ability to manipulate DNS responses could direct the gem command towards a different domain.
