Xen was updated to fix several security issues :
A xen HVM guest destroy p2m teardown host DoS vulnerability was fixed, where malicious guest could lock/crash the host. (CVE-2012-3433)
A xen HVM guest user mode MMIO emulation DoS was fixed.
(CVE-2012-3432)
The xen pv bootloader doesn’t check the size of the bzip2 or lzma compressed kernel, leading to denial of service (crash). (CVE-2012-2625)
Also the following bug in XEN was fixed :
Xen HVM DomU crash during Windows Server 2008 R2 install, when maxmem > memory This update also included bugfixes for:. (bnc#746702)
vm-install: - bnc#762963 - ReaR: Unable to recover a paravirtualized XEN guest
