The remote Solaris system is missing necessary patches to address security updates :
MIT Kerberos 5 (aka krb5) before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read and application crash) by injecting invalid tokens into a GSSAPI application session. (CVE-2014-4341)
MIT Kerberos 5 (aka krb5) 1.7.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read or NULL pointer dereference, and application crash) by injecting invalid tokens into a GSSAPI application session. (CVE-2014-4342)
