DEBIAN-CVE-2014-7156

The x86emulate function in arch/x86/x86emulate/x86emulate.c in Xen 3.3.x through 4.4.x does not check the supervisor mode permissions for instructions that generate software interrupts, which allows local HVM guest users to cause a denial of service guest crash via unspecified vectors...

Improper MSR range used for x2APIC emulation

ISSUE DESCRIPTION The MSR range specified for APIC use in the x2APIC access model spans 256 MSRs. Hypervisor code emulating read and write accesses to these MSRs erroneously covered 1024 MSRs. While the write emulation path is written such that accesses to the extra MSRs would not have any bad...

[SECURITY] Fedora 21 Update: qemu-2.1.2-2.fc21

QEMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation. QEMU has two operating modes: Full system emulation. In this mode, QEMU emulates a full system for example a PC, including a processor and various peripherials. It can be used ...

Missing privilege level checks in x86 emulation of software interrupts

ISSUE DESCRIPTION The emulation of instructions which generate software interrupts fails to perform supervisor mode permission checks. However these instructions are not usually handled by the emulator. Exceptions to this are - when a memory operand implicit for the affected instructions lives in...
