Descriptions

lib/gssapi/spnego/spnego_mech.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 SPNEGO packet that is mishandled during a gss_inquire_context call.

lib/gssapi/spnego/spnego_mech.c en MIT Kerberos 5 (también conocido como krb5) en versiones anteriores a 1.14 confía en un manejo de contexto inapropiado, lo que permite a atacantes remotos provocar una denegación de servicio (lectura de puntero incorrecto y caída de proceso) a través de un paquete SPNEGO manipulado que no es manejado correctamente durante una llamada a gss_inquire_context.
