Summary

Hyper-V in Microsoft Windows Server 2008 SP2 and R2 SP1, Windows 8, Windows 8.1, and Windows Server 2012 Gold and R2 does not properly initialize guest OS system data structures, which allows guest OS users to execute arbitrary code on the host OS by leveraging guest OS privileges, aka "Hyper-V System Data Structure Vulnerability."

descriptionThe remote Windows host is affected by multiple remote code execution vulnerabilities in Hyper-V : - An error exists in how Hyper-V handles packet size memory initialization in guest virtual machines. An authenticated attacker with access to a guest virtual machine can exploit this by running a specially crafted application to execute arbitrary code in a host context. (CVE-2015-2361) - An error exists in how Hyper-V initializes system data structures in guest virtual machines. An authenticated attacker with access to a guest virtual machine can exploit this by running a specially crafted application to execute arbitrary code in a host context. (CVE-2015-2362)
