DESCRIPTION:
A vulnerability has been reported in Kerberos, which can be exploited
by malicious users to cause a DoS (Denial of Service).

The vulnerability is caused due to a NULL pointer dereference error
when processing certain Kerberos AP-REQ authenticators, which can be
exploited to cause a crash in e.g. kadmind or other applications
linked against the GSS-API library by sending an AP-REQ authenticator
with a missing checksum field.

The vulnerability is reported in all releases including krb5-1.8.1.

SOLUTION:
Apply patches. Reportedly, the vulnerability will be fixed in the
upcoming krb5-1.8.2 release and an upcoming krb5-1.7 series release.
