A certain Red Hat patch for net/ipv4/route.c in the Linux kernel
2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to
cause a denial of service (deadlock) via crafted packets that force
collisions in the IPv4 routing hash table, and trigger a routing
"emergency" in which a hash chain is too long. NOTE: this is related
to an issue in the Linux kernel before 2.6.31, when the kernel routing
cache is disabled, involving an uninitialized pointer and a panic.
