Red Hat Security Advisory 2013-0168-01

Posted Jan 23, 2013

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-0168-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the Xen hypervisor implementation did not perform range checking on the guest provided values in multiple hypercalls. A privileged guest user could use this flaw to trigger long loops, leading to a denial of service. It was found that when running a 32-bit binary that uses a large number of shared libraries, one of the libraries would always be loaded at a predictable address in memory. An attacker could use this flaw to bypass the Address Space Layout Randomization security feature.
