OracleVM 3.1 : xen (OVMSA-2013-0041)

high Nessus Plugin ID 79509

Synopsis

The remote OracleVM host is missing one or more security updates.

Description

The remote OracleVM system is missing necessary patches to address critical security updates :

- libxc: limit cpu values when setting vcpu affinity When support for pinning more than 64 cpus was added, check for cpu out-of-range values was removed. This can lead to subsequent out-of-bounds cpumap array accesses in case the cpu number is higher than the actual count.
This patch returns the check. This is CVE-2013-2072 / XSA-56 (CVE-2013-2072)

Solution

Update the affected xen / xen-devel / xen-tools packages.
