Descriptions
The slapper function in chkrootkit before 0.50 does not properly quote file paths, which allows local users to execute arbitrary code via a Trojan horse executable. NOTE: this is only a vulnerability when /tmp is not mounted with the noexec option.
La función slapper en chkrootkit anterior a 0.50 no cita debidamente las rutas de los ficheros de citas, lo que permite a usuarios locales ejecutar código arbitrario a través de un troyano ejecutable. NOTA: esto solamente es una vulnerabilidad cuando /tmp no está montado con la opción noexec.
Chkrootkit before 0.50 will run any executable file named /tmp/update as root, allowing a trivial privsec. WfsDelay is set to 24h, since this is how often a chkrootkit scan is scheduled by default.
