Linux kernel 2.6.20.7 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.20.7 Previous kernel had most of this update already applied.
Linux kernel 2.6.20.8 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.20.8 Fixes CVE-2007-1861
Linux kernel 2.6.20.9 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.20.9 Fixes CVE-2007-2242
Linux kernel 2.6.20.10 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.20.10 Fixes two bugs introduced by the two previous updates.
CVE-2007-1861: The netlink protocol has an infinite recursion bug that allows users to cause a kernel crash.
CVE-2007-2242: The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
