RubyGems Escape sequence injection in errors
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| RubyGems | rubygems-update | >= 2.6.0, < 2.7.9 | 2.7.9 |
| RubyGems | rubygems-update | >= 3.0.0, < 3.0.2 | 3.0.2 |
Details
As written in the advisory (Markdown source, shown as plain text).
An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::CommandManager#run calls alert_error without escaping, escape sequence injection is possible. (There are many ways to cause an error.)
