lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) before 1.14 relies on an inappropriate context handle, which allows remote attackers to cause a denial of service (incorrect pointer read and process crash) via a crafted IAKERB packet that is mishandled during a gss_inquire_context call.
A type-confusion flaw was discovered in MIT Kerberos, where it incorrectly deals with IAKERB context handles.
If an application calls gss_inquire_context() on a partially-established IAKERB context, an unauthenticated remote attacker could possibly exploit the flaw to crash the application (denial of service) by sending it a specially crafted IAKERB packet.
