Prior to version 7.5, due to heap Use-After-Free, Squid is vulnerable to Denial of Service when handling ICP traffic. This problem allows a remote attacker to perform a reliable and repeatable Denial of Service attack against the Squid service using ICP protocol. This attack is limited to Squid deployments that explicitly enable ICP support (i.e. configure non-zero `icp_port`). This problem _cannot_ be mitigated by denying ICP queries using `icp_access` rules. Version 7.5 contains a patch."},{"lang":"es","value":"Squid es un proxy de almacenamiento en caché para la Web. Antes de la versión 7.5, debido a un uso después de liberación (Use-After-Free) en el heap, Squid es vulnerable a denegación de servicio al manejar tráfico ICP. Este problema permite a un atacante remoto realizar un ataque de denegación de servicio fiable y repetible contra el servicio Squid utilizando el protocolo ICP. Este ataque se limita a implementaciones de Squid que habilitan explícitamente el soporte ICP (es decir, configuran un 'icp_port' distinto de cero).
