+++ This bug was initially created as a clone of Bug #171386 +++ CVE-2005-3275 states: The NAT code (1) ip_nat_proto_tcp.c and (2) ip_nat_proto_udp.c in Linux kernel 2.6 before 2.6.13 and 2.4 before 2.4.32-rc1 incorrectly declares a variable to be static, which allows remote attackers to cause a denial of service (memory corruption) by causing two packets for the same protocol to be NATed at the same time, which leads to memory corruption. http://linux.bkbits.net:8080/linux-2.4/cset@42ed94a6GH4Evdcy1opShq3w0GHUWQ This issue was already fixed in EL4 in linux-2.6.12-network.patch but not in EL2.1 which looks vulnerable to this issue.
