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.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| rubygems-update | lt | 3.0.2 | |
| rubygems-update | lt | 2.7.9 |
