fix for LDAP issues and other authorization flaws

Related CVE CVE-2015-2694 CVE-2018-5729 CVE-2018-5730 CVE-2018-20217

krb5, a MIT Kerberos implementation had several flaws in LDAP DN checking, which could be used to circumvent a DN containership check by supplying special parameters to some calls. Further an attacker could crash the KDC by making S4U2Self requests.

For Debian 7 Wheezy, these problems have been fixed in version 1.10.1+dfsg-5+deb7u10.

We recommend that you upgrade your krb5 packages.
