        Log Message:
        sudo is nominated for crapware of the year.  Now at version 1.6.8pl4!

        Just as for pl2, changes are about environment sanitizing, meaning
        there are possible security issues with current versions.

        Changes:

        550) The CDPATH variable is now stripped from the environment passed
             to the program to be executed.
        551) Fix temp file generation on systems where the _PATH_VARTMP macro
             lacks a trailing slash.
        552) The KRB5CCNAME environment variable is preserved during sudo
             execution for password lookups that use GSSAPI.
