The gss_userok function in appl/ftp/ftpd/gss_userok.c in Heimdal 0.7.2 does
not allocate memory for the ticketfile pointer before calling free, which
allows remote attackers to have an unknown impact via an invalid username.
NOTE: the vulnerability was originally reported for ftpd.c, but this is
incorrect.
