Overview

sup is a console-based email client for people with a lot of email. Affected versions of this gem do not sanitize email attachment content when using quotes (',") around filename or content_type which is already escaped using Ruby Shellwords.escape - this means that the string (content_type, filename) is intended to be used without any further quotes. This may allow a context-dependent attacker to execute arbitrary commands.
