Posted Mar 19, 2013

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1767-1 - Andrew Cooper of Citrix reported a Xen stack corruption in the Linux kernel. An unprivileged user in a 32bit PVOPS guest can cause the guest kernel to crash, or operate erroneously. A failure to validate input was discovered in the Linux kernel's Xen netback (network backend) driver. A user in a guest OS may exploit this flaw to cause a denial of service to the guest OS and other guest domains. Various other issues were also addressed.
