bounds checking when it copied the 'user' and 'realm' arguments into
local buffers. If this program is used in remotely callable CGI
scripts, this could be exploited by a remote attacker to execute
arbitrary code with the privileges of the CGI script.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
