Description

A resource-access flaw was discovered in krb5; the SPNEGO mechanism operates under an incorrect assumption when dealing with its context handles. If an application calls gss_inquire_context() on a partially-established SPNEGO context, an unauthenticated, remote attacker could possibly exploit this flaw by sending a specially crafted SPNEGO packet and crashing the system.
