CVE-2013-2072 xen: Buffer overflow in xencontrol Python bindings affecting xend
The Python bindings for the xc_vcpu_setaffinity call do not properly check their inputs. Systems which allow untrusted administrators to configure guest vcpu affinity may be exploited to trigger a buffer
overrun and corrupt memory.
An attacker who is able to configure a specific vcpu affinity via a toolstack which uses the Python bindings is able to exploit this issue.
Exploiting this issue leads to memory corruption which may result in a DoS against the system by crashing the toolstack. The possibility of code execution (privilege escalation) has not been ruled out.
The xend toolstack passes a cpumap to this function without sanitization. xend allows the cpumap to be configured via the guest configuration
