The remote host is affected by the vulnerability described in GLSA-200409-08
(Ruby: CGI::Session creates files insecurely)
The CGI::Session::FileStore implementation (and presumably
CGI::Session::PStore), which allow data associated with a particular
Session instance to be written to a file, writes to a file in /tmp with no
regard for secure permissions. As a result, the file is left with whatever
the default umask permissions are, which commonly would allow other local
users to read the data from that session file.
Depending on the default umask, any data stored using these methods could
be read by other users on the system.
By changing the default umask on the system to not permit read access to
other users (e.g. 0700), one can prevent these files from being readable by
