rubygems: Delete directory using symlink when decompressing tar

A Directory Traversal issue was discovered in RubyGems 2.7.6 and later through 3.0.2. Before making new directories or touching files which now include path-checking code for symlinks, it would delete the target destination. If that destination was hidden behind a symlink, a malicious gem could...

rubygems: Escape sequence injection vulnerability in gem owner

An issue was discovered in RubyGems 2.6 and later through 3.0.2. The gem owner command outputs the contents of the API response directly to stdout. Therefore, if the response is crafted, escape sequence injection may occur...

Man-in-the-Middle (MitM)

RubyGems is the Ruby standard for publishing and managing third-party libraries. It was found that, when using RubyGems, the connection could be redirected from HTTPS to HTTP. This could lead to a user believing they are installing a gem via HTTPS, when the connection may have been silently...
