Fedora 26: FEDORA-2017-2962e58478 Moderate: Heimdal NULL Pointer Threat

Kerberos 5 is a network authentication and single sign-on system.

Heimdal is a free Kerberos 5 implementation without export restrictions

written from the spec (rfc1510 and successors) including advanced features

like thread safety, IPv6, master-slave replication of Kerberos Key

Distribution Center server and support for ticket delegation (S4U2Self,

S4U2Proxy).

This package can coexist with MIT Kerberos 5 packages. Hesiod is disabled

by default since it is deemed too big a security risk by the packager.

Update to 7.5.0 GA release (CVE-2017-17439)
