Descriptions

nf_conntrack in netfilter in the Linux kernel before 2.6.20.3 does not set nfctinfo during reassembly of fragmented packets, which leaves the default value as IP_CT_ESTABLISHED and might allow remote attackers to bypass certain rulesets using IPv6 fragments.

nf_conntrack en netfilter en el kernel de Linux anterior a 2.6.20.3 no fija nfctinfo durante el nuevo re-ensamble de paquetes fragmentados, lo cual deja el valor por defecto como IP_CT_ESTABLISHED y permitiría a atacantes remotos evitar ciertas reglas de asignación utilizando fragmentos IPv6.
