Synopsis: Important: kernel security and bug fix update
Issue Date: 2013-03-12
CVE Numbers: CVE-2013-0228
CVE-2013-0268
—
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 system must be rebooted for this update to take effect.
