Summary: Updated kernel packages that fix multiple security issues and two bugs are now available for Red Hat Enterprise Linux 5.3 Extended Update Support. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5.3.z server) - i386, ia64, noarch, ppc, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * a flaw was found in the IPv6 Extension Header (EH) handling implementation in the Linux kernel. The skb->dst data structure was not properly validated in the ipv6_hop_jumbo() function. This could possibly lead to a remote denial of service. (CVE-2007-4567, Important) * a flaw was found in each of the following Intel PRO/1000 Linux drivers in the Linux kernel: e1000 and e1000e. A remote attacker using packets larger than the MTU could bypass the existing fragment check, resulting in partial, invalid frames being passed to the network stack. These flaws could also possibly be used to trigger a remote denial of service. (CVE-2009-4536, CVE-2009-4538, Important) * a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. Receiving overly-long frames with a certain revision of the network cards supported by this driver could possibly result in a remote denial of service. (CVE-2009-4537, Important) This update also fixes the following bugs: * on certain hardware, the igb driver was unable to detect link statuses correctly for Serializer-Deserializer (SERDES) interface Ethernet ports. This may have caused problems for network interface bonding, such as failover not occurring. (BZ#548023) * in certain situations, kdump occasionally dumped a vmcore file with no registers on Intel Itanium systems that were under high disk I/O load. In these cases, this prevented the kernel stack backtrace in the vmcore from being viewed with the crash utility. (BZ#542581) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 542581 - kdump corefile cannot be backtraced in IA64 [rhel-5.3.z] 548023 - EL5.3: igb driver fails to detect link status change on SERDES interface [rhel-5.3.z] 548641 - CVE-2007-4567 kernel: ipv6_hop_jumbo remote system crash 550907 - CVE-2009-4537 kernel: r8169 issue reported at 26c3 551214 - CVE-2009-4538 kernel: e1000e frame fragment issue 552126 - CVE-2009-4536 kernel: e1000 issue reported at 26c3 6.
