Xen has been updated to fix six security issues :
Guest effectable page reference leak in MMU_MACHPHYS_UPDATE handling (CVE-2014-9030).
Insufficient bounding of ‘REP MOVS’ to MMIO emulated inside the hypervisor (CVE-2014-8867).
Missing privilege level checks in x86 emulation of far branches (CVE-2014-8595).
Guest user mode triggerable VM exits not handled by hypervisor (bnc#903850).
Missing privilege level checks in x86 HLT, LGDT, LIDT, and LMSW emulation (CVE-2014-7155).
Hypervisor heap contents leaked to guests (CVE-2014-4021).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
