Red Hat Security Advisory 2012-0720-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the Xen hypervisor implementation as shipped with Red Hat Enterprise Linux 5 did not properly restrict the syscall return addresses in the sysret return path to canonical addresses. An unprivileged user in a 64-bit para-virtualized guest, that is running on a 64-bit host that has an Intel CPU, could use this flaw to crash the host or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level.

Red Hat Security Advisory 2012-0480-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: A flaw in the xfrm6_tunnel_rcv() function in the Linux kernel's IPv6 implementation could lead to a use-after-free or double free flaw in tunnel6_rcv(). A remote attacker could use this flaw to send specially-crafted packets to a target system that is using IPv6 and also has the xfrm6_tunnel kernel module loaded, causing it to crash.
