GSD-2019-8324
Vulnerability from gsd - Updated: 2019-03-05 00:00Details
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.
