How to fix?

Upgrade Debian:9 krb5 to version 1.13.2+dfsg-3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream krb5 package and not the krb5 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

The build_principal_va function in lib/krb5/krb/bld_princ.c in MIT Kerberos 5 (aka krb5) before 1.14 allows remote authenticated users to cause a denial of service (out-of-bounds read and KDC crash) via an initial '\0' character in a long realm field within a TGS request.
