ruby is vulnerable to privilege escalation. It was found that WEBrick (the Ruby HTTP server toolkit) did not filter terminal escape sequences from its log files. A remote attacker could use specially-crafted HTTP requests to inject terminal escape sequences into the WEBrick log files. If a victim viewed the log files with a terminal emulator, it could result in control characters being executed with the privileges of that user.
