"The remote host is affected by the vulnerability described in GLSA-201201-14
(MIT Kerberos 5 Applications: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in MIT Kerberos 5
      Applications:
      An error in the FTP daemon prevents it from dropping its initial
        effective group identifier (CVE-2011-1526).
      A boundary error in the telnet daemon and client could cause a buffer
        overflow (CVE-2011-4862).
  
Impact :

    An unauthenticated remote attacker may be able to execute arbitrary code
      with the privileges of the user running the telnet daemon or client.
      Furthermore, an authenticated remote attacker may be able to read or
      write files owned by the same group as the effective group of the FTP
      daemon.
  
Workaround :

    There is no known workaround at this time."
