CVE-2022-48338

An issue was discovered in GNU Emacs through 28.2. In ruby-mode.el, the
ruby-find-library-file function has a local command injection
vulnerability. The ruby-find-library-file function is an interactive
function, and bound to C-c C-f. Inside the function, the external command
gem is called through shell-command-to-string, but the feature-name
parameters are not escaped. Thus, malicious Ruby source files may cause
commands to be executed.
