OracleVM 3.1 : xen (OVMSA-2013-0043)

The remote OracleVM system is missing necessary patches to address critical security updates : - x86/xsave: properly check guest input to XSETBV Other than the HVM emulation path, the PV case so far failed to check that YMM state requires SSE state to be enabled, allowing for a GP to occur upon...

CVE-2013-1442

CVE-2013-1442 affects Xen 4.0–4.3.x on CPUs with AVX or LWP. The issue is that XSAVE/XRSTOR state extension of a saved/restored vCPU may leave residual data in registers after touching other extended registers, enabling a local guest OS to read sensitive information from those registers. The vuln...

CVE-2013-1442: Exposure of Sensitive Information to an Unauthorized Actor

Hypervisor crash due to missing exception recovery on XRSTOR

ISSUE DESCRIPTION Processors do certain validity checks on the data passed to XRSTOR. While the hypervisor controls the placement of that memory block, it doesn't restrict the contents in any way. Thus the hypervisor exposes itself to a fault occurring on XRSTOR. Other than for FXRSTOR, which...

Information leak on XSAVE/XRSTOR capable AMD CPUs

ISSUE DESCRIPTION On AMD processors supporting XSAVE/XRSTOR family 15h and up, when an exception is pending, these instructions save/restore only the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR. This allows one domain to determine portions of the state of floating point instructions of othe...

CVE-2012-4461

CVE-2012-4461 overview: The Linux kernel KVM subsystem (pre-3.6.9) on hosts using qemu userspace without XSAVE is vulnerable. A local attacker can trigger a denial of service (kernel OOPS) by calling KVM_SET_SREGS to enable the X86_CR4_OSXSAVE bit in the guest CR4, then issuing KVM_RUN. The conne...
