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:10 relevant fixed versions and status.

server/server_stubs.c in the kadmin protocol implementation in MIT Kerberos 5 (aka krb5) 1.10 before 1.10.1 does not properly restrict access to (1) SET_STRING and (2) GET_STRINGS operations, which might allow remote authenticated administrators to modify or read string attributes by leveraging the global list privilege.
