REDHAT-BUG-910883
First published: Wed Feb 13 2013(Updated: )
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. <a href="https://access.redhat.com/security/cve/CVE-2013-0216">CVE-2013-0216</a> is a failure to sanity check the ring producer/consumer pointers which can allow a guest to cause netback to loop for an extended period preventing other work from occurring. <a href="https://access.redhat.com/security/cve/CVE-2013-0217">CVE-2013-0217</a> is a memory leak on an error path which is guest triggerable. A malicious guest with access to PV network devices can mount a DoS affecting the entire system. Acknowledgements: Red Hat would like to thank the Xen project for reporting this issue.
