How to fix?

Upgrade Ubuntu:14.04 krb5 to version 1.12+dfsg-2ubuntu5.2 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 Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

MIT Kerberos 5 (aka krb5) through 1.13.1 incorrectly expects that a krb5_read_message data field is represented as a string ending with a '\0' character, which allows remote attackers to (1) cause a denial of service (NULL pointer dereference) via a zero-byte version string or (2) cause a denial of service (out-of-bounds read) by omitting the '\0' character, related to appl/user_user/server.c and lib/krb5/krb/recvauth.c.
