Summary

The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory.

Insight

Insight

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * A flaw was found in the way the xen_iret() function in the Linux kernel used the DS (the CPU's Data Segment) register. A local, unprivileged user in a 32-bit, para-virtualized Xen hypervisor guest could use this flaw to crash the guest or, potentially, escalate their privileges. (CVE-2013-0228, Important) * A flaw was found in the way file permission checks for the '/dev/cpu/[x]/msr' files were performed in restricted root environments (for example, when using a capability-based security model). A local user with the ability to write to these files could use this flaw to escalate their privileges to kernel level, for example, by writing to the SYSENTER_EIP_MSR register. (CVE-2013-0268, Important) The CVE-2013-0228 issue was discovered by Andrew Jones of Red Hat. This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.
