Red Hat Bugzilla – Bug 910874
CVE-2013-0231 kernel: xen: pciback DoS via not rate limited log messages
Last modified: 2015-02-16 10:46:35 EST
Xen's PCI backend drivers in Linux allow a guest with assigned PCI device(s) to cause a DoS through a flood of kernel messages, potentially affecting other
domains in the system.
A malicious guest with passed through PCI devices can mount a DoS affecting the entire system.
Red Hat would like to thank the Xen project for reporting this issue.
