DEBIAN-CVE-2014-9065

common/spinlock.c in Xen 4.4.x and earlier does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service write denial or NMI watchdog timeout and host crash via a large number of read requests, a different vulnerability to CVE-2014-9066...

Code injection

The compatibility mode hypercall argument translation in Xen 3.3.x through 4.4.x, when running on a 64-bit hypervisor, allows local 32-bit HVM guests to cause a denial of service host crash via vectors involving altering the high halves of registers while in 64-bit mode...

CVE-2014-8867

The acceleration support for the "REP MOVS" instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O MMIO emulated in the hypervisor, which allows local HVM guests to cause a denial of service host crash via unspecified vectors...

Excessive checking in compatibility mode hypercall argument translation

ISSUE DESCRIPTION The hypercall argument translation needed for 32-bit guests running on 64-bit hypervisors performs checks on the final register state. These checks cover all registers potentially holding hypercall arguments, not just the ones actually doing so for the hypercall being processed,...

Guest effectable page reference leak in MMU_MACHPHYS_UPDATE handling

ISSUE DESCRIPTION An error handling path in the processing of MMUMACHPHYSUPDATE failed to drop a page reference which was acquired in an earlier processing step. IMPACT Malicious or buggy stub domain kernels or tool stacks otherwise living outside of Domain0 can mount a denial of service attack...

DEBIAN-CVE-2014-8594

The dommuupdate function in arch/x86/mm.c in Xen 4.x through 4.4.x does not properly restrict updates to only PV page tables, which allows remote PV guests to cause a denial of service NULL pointer dereference by leveraging hardware emulation services for HVM guests using Hardware Assisted Paging...

CVE-2014-8594

CVE-2014-8594 affects Xen 4.x up to 4.4.x (Xen hypervisor) where do_mmu_update in arch/x86/mm.c does not properly restrict updates to PV page tables. This enables remote PV guests to trigger a denial of service via a NULL pointer dereference by leveraging hardware emulation services for HVM guest...

Insufficient restrictions on certain MMU update hypercalls

ISSUE DESCRIPTION MMU update operations targeting page tables are intended to be used on PV guests only. The lack of a respective check made it possible for such operations to access certain function pointers which remain NULL when the target guest is using Hardware Assisted Paging HAP. IMPACT...
