FreeBSD : rubygems -- request hijacking vulnerability (a0089e18-fc9e-11e4-bc58-001e67150279)

Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

Jonathan Claudius reports :

RubyGems provides the ability of a domain to direct clients to a
separate host that is used to fetch gems and make API calls against.
This mechanism is implemented via DNS, specifically a SRV record
_rubygems._tcp under the original requested domain.

RubyGems did not validate the hostname returned in the SRV record
before sending requests to it. This left clients open to a DNS hijack
attack, whereby an attacker could return a SRV of their choosing and
get the client to use it.
