The SuiteLink Service (aka slssvc.exe) in WonderWare SuiteLink before 2.0 Patch 01, as used in WonderWare InTouch 8.0, allows remote attackers to cause a denial of service (NULL pointer dereference and service shutdown) and possibly execute arbitrary code via a large length value in a Registration packet to TCP port 5413, which causes a memory allocation failure. El servicio SuiteLink Service (también conocido como slssvc.exe) en WonderWare SuiteLink anterior a 2.0 Patch 01, como el usado en WonderWare InTouch 8.0, permite a atacantes remotos provocar una denegación de servicio(referencia a puntero nulo y apagado de servicio) y posiblemente ejecutar código de su elección mediante un valor de longitud largo en un paquete Registration (registro) al puerto TCP 5413, que provoca un fallo de asignación de memoria. • https://www.exploit-db.com/exploits/6474 http://secunia.com/advisories/30063 http://www.coresecurity.com/?action=item&id=2187 http://www.kb.cert.org/vuls/id/596268 http://www.securityfocus.com/archive/1/491623/100/0/threaded http://www.securityfocus.com/bid/28974 http://www.securitytracker.com/id?1019966 https://exchange.xforce.ibmcloud.com/vulnerabilities/42221 • CWE-399: Resource Management Errors •
