Descriptions

PolicyKit (aka polkit) before 0.113 allows local users to cause a denial of service (memory corruption and polkitd daemon crash) and possibly gain privileges via unspecified vectors, related to "javascript rule evaluation."

PolicyKit (también conocido como polkit) en versiones anteriores a 0.113 permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída del demonio polkitd) y posiblemente obtener privilegios a través de vectores no especificados, relacionado con 'regla de evaluación javascript'.

A denial of service flaw was found in how polkit handled authorization requests. A local, unprivileged user could send malicious requests to polkit, which could then cause the polkit daemon to corrupt its memory and crash.
