Descriptions

A heap overflow vulnerability exists within FactoryTalk Linx Version 6.11 and prior. This vulnerability could allow a remote, unauthenticated attacker to send malicious set attribute requests, which could result in the leaking of sensitive information. This information disclosure could lead to the bypass of address space layout randomization (ASLR).

Se presenta una vulnerabilidad de desbordamiento de la pila en FactoryTalk Linx versiones 6.11 y anteriores. Esta vulnerabilidad podría permitir a un atacante remoto no autenticado enviar peticiones de atributos de configuración maliciosos, lo que podría resultar en un filtrado de información confidencial. Esta divulgación de información podría conllevar a una omisión de la aleatorización del diseño de espacio de direcciones (ASLR)
