Описание
net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux kernel before 2.6.34, when the nf_conntrack_ipv6 module is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets.
Отчет
This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5 as they did not include support for netfilter's ipv6 connection tracking module. This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux MRG as they already contain the upstream commit that fixes this issue.
