Descriptions

SystemTap 1.4, when unprivileged (aka stapusr) mode is enabled, allows local users to cause a denial of service (divide-by-zero error and OOPS) via a crafted ELF program with DWARF expressions that are not properly handled by a stap script that performs stack unwinding (aka backtracing).

SystemTap 1.4, (también conocido como stapusr) cuando el modo no privilegiado está habilitado, permite a usuarios locales provocar una denegación de servicio (error de división por cero y OOPS) a través de un programa de ELF modificado con expresiones DWARF que no están bien mipulado por una secuencia de comandos STAP que realiza acondicionamiento de la pila (también conocido como rastreo).
