The remote Scientific Linux host is missing one or more security
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.
The system must be rebooted for this update to take effect.
