openSUSE 10 Security Update : xen (xen-2156)

High Nessus Plugin ID 27482


The remote openSUSE host is missing a security update.


This update fixes an issue on x86_64 in which a user-level application can crash the guest OS when running Xen.

The AC (alignment check) flag in RFLAGS was not being cleared on entry to the guest kernel, causing unwanted faults because the kernel runs in ring 3 on Xen.


Update the affected xen packages.
