There is no fixed version for rubysl-tmpdir.
Overview
rubysl-tmpdir is a ruby standard library for tmpdir.
Affected versions of this package are vulnerable to Directory Traversal. Dir.mktmpdir method introduced by tmpdir library accepts the prefix and the suffix of the directory which is created as the first parameter. The prefix can contain relative directory specifiers "../", so this method can be used to target any directory. So, if a script accepts an external input as the prefix, and the targeted directory has inappropriate permissions or the ruby process has inappropriate privileges, the attacker can create a directory or a file at any directory.
