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.

PolicyKit is a toolkit for defining and handling authorizations. 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. All polkit users should upgrade to these updated packages, which contain a backported patch to correct this issue. The system must be rebooted for this update to take effect.
