Descriptions

Possible system denial of service in case of arbitrary changing Firefox browser parameters. An attacker could change specific Firefox browser parameters file in a certain way and then reboot the system to make the system unbootable.

Una posible denegación de servicio del sistema en caso de cambio arbitrario de los parámetros del navegador Firefox. Un atacante podría cambiar un archivo específico de parámetros del navegador Firefox de una manera determinada y luego reiniciar el sistema para hacer que el sistema no pueda arrancar

This vulnerability allows local attackers to create a denial-of-service condition on affected installations of Kaspersky Total Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within Kaspersky Lab Launcher. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.
