Red Hat Security Advisory 2012-0721-01

Posted Jun 12, 2012

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0721-01 - 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.
