USN-2396-1: Linux kernel vulnerabilities

Nadav Amit reported that the KVM Kernel Virtual Machine mishandles noncanonical addresses when emulating instructions that change the rip Instruction Pointer. A guest user with access to I/O or the MMIO can use this flaw to cause a denial of service system crash of the guest. CVE-2014-3647 A flaw...

DEBIAN-CVE-2014-7188

The hvmmsrreadintercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR range for x2APIC emulation, which allows local HVM guests to cause a denial of service host crash or read data from the hypervisor or other guests 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...
