Linux pciback DoS via not rate limited log messages.

ISSUE DESCRIPTION Xen's PCI backend drivers in Linux allow a guest with assigned PCI devices to cause a DoS through a flood of kernel messages, potentially affecting other domains in the system. IMPACT A malicious guest can mount a DoS affecting the entire system. VULNERABLE SYSTEMS All systems...

Linux netback DoS via malicious guest ring.

ISSUE DESCRIPTION The Xen netback implementation contains a couple of flaws which can allow a guest to cause a DoS in the backend domain, potentially affecting other domains in the system. CVE-2013-0216 is a failure to sanity check the ring producer/consumer pointers which can allow a guest to...
