Descriptions

VMware Horizon Client for Windows (5.x before 5.5.0) contains a denial-of-service vulnerability due to a file system access control issue during install time. Successful exploitation of this issue may allow an attacker to overwrite certain admin privileged files through a symbolic link attack at install time. This will result into a denial-of-service condition on the machine where Horizon Client for Windows is installed.

VMware Horizon Client para Windows (versiones 5.x anteriores a 5.5.0) contiene una vulnerabilidad de denegación de servicio debido a un problema de control de acceso del sistema de archivos durante el tiempo de instalación. Una explotación con éxito de este problema puede permitir a un atacante sobrescribir determinados archivos con privilegios de administrador por medio de un ataque de enlace simbólico en el momento de la instalación. Esto resultará en una condición de denegación de servicio en la máquina donde Horizon Client para Windows está instalado
