What is CVE-2012-3515?
CVE-2012-3515 is a high-severity memory corruption vulnerability in Canonical Ubuntu Linux, published on 23 Nov 2012. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Qemu, as used in Xen 4.0, 4.1 and possibly other products, when emulating certain devices with a virtual console backend, allows local OS guest users to gain privileges via a crafted escape VT100 sequence that triggers the overwrite of a "device model's address space."
