Descriptions

The build_principal_va function in lib/krb5/krb/bld_princ.c in MIT Kerberos 5 (aka krb5) before 1.14 allows remote authenticated users to cause a denial of service (out-of-bounds read and KDC crash) via an initial '\0' character in a long realm field within a TGS request.

La función build_principal_va en lib/krb5/krb/bld_princ.c en MIT Kerberos 5 (también conocido como krb5) en versiones anteriores a 1.14 permite a usuarios remotos autenticados provocar una denegación de servicio (lectura fuera de rango y caída de KDC) a través de un carácter inicial '\0' en un campo realm largo dentro de una solicitud TGS.
