Descriptions
A security flaw was found in the ip_frag_reasm() function in net/ipv4/ip_fragment.c in the Linux kernel from 4.19-rc1 to 4.19-rc3 inclusive, which can cause a later system crash in ip_do_fragment(). With certain non-default, but non-rare, configuration of a victim host, an attacker can trigger this crash remotely, thus leading to a remote denial-of-service.
Se ha encontrado un error de seguridad en la función ip_frag_reasm() en net/ipv4/ip_fragment.c en el kernel de Linux, desde la versión 4.19-rc1 a la 4.19-rc3, lo que puede provocar un posterior cierre inesperado en ip_do_fragment(). Con ciertas configuraciones que no son por defecto, pero que no son raras, de un host víctima, un atacante puede desencadenar este cierre remotamente, conduciendo así a una denegación de servicio (DoS) remota.
