Language:

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.
