CVE-2016-9378

Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service guest crash by leveraging an incorrect choice for software interrupt delivery...

memory leak when destroying guest without PT devices

ISSUE DESCRIPTION Certain internal state is set up, during domain construction, in preparation for possible pass-through device assignment. On ARM and AMD V-i hardware this setup includes memory allocation. On guest teardown, cleanup was erroneously only performed when the guest actually had a...

Xen Intel VMX hvmemul_vmfunc() NULL Pointer Dereference DoS (XSA-203)

According to its self-reported version number, the Xen hypervisor installed on the remote host is missing a security update. It is, therefore, affected by a NULL pointer dereference flaw due to a failure to utilize necessary NULL checks before doing indirect function calls through the hvmemulvmfu...

CVE-2016-10025

CVE-2016-10025 affects the Xen hypervisor when running on x86 with AMD SVM (VMFUNC emulation) and allows local HVM guests to crash the hypervisor due to a missing NULL pointer check in hvmemul_vmfunc(). Public references in the connected data show Xen versions 4.6.x–4.8.x as vulnerable and descri...

Security update for xen (important)

This updates xen to version 4.4.406 to fix the following issues: - An unprivileged user in a guest could gain guest could escalate privilege to that of the guest kernel, if it had could invoke the instruction emulator. Only 64-bit x86 HVM guest were affected. Linux guest have not been vulnerable...

x86: missing NULL pointer check in VMFUNC emulation

ISSUE DESCRIPTION When support for the Intel VMX VMFUNC leaf 0 was added, a new optional function pointer hvmemulvmfunc was added to the hvmemulateops table. As is intended, that new function pointer is NULL on non-VMX hardware, including AMD SVM hardware. However at a call site, the necessary NU...

Researchers Question Security in AMD's Upcoming Zen Chips

As more computing heads to the clouds, security researchers are questioning the security of virtual machine control panels called hypervisors. One of the first hardware-based solutions to address these concerns will be deployed by chip manufacturer AMD, called Secure Encrypted Virtualization. The...
