CVE-2019-8324

Published: 27 March 2019

An issue was discovered in RubyGems 2.6 and later through 3.0.2. A crafted gem with a multi-line name is not handled correctly. Therefore, an attacker could inject arbitrary code to the stub line of gemspec, which is eval-ed by code in ensure_loadable_spec during the preinstall check.

From the Ubuntu security team

It was discovered that RubyGems as embedded in JRuby did not properly handle multi-line gem names. If a user were tricked into installing a malicious gem, an attacker could execute arbitrary code.
