The vulnerability of the QEMU hardware emulation software allows a hacker to execute any code on the host operating system.

The vulnerability of the pitioportread function in the QEMU hardware emulation software is caused by buffer overflow. Exploiting this vulnerability allows a local attacker to execute arbitrary code on the host operating system...

The vulnerability of the QEMU hardware emulation software allows a hacker to execute arbitrary code.

The vulnerability of the QEMU hardware emulation software arises from an overflow in the buffer of dynamic memory. Exploiting this vulnerability allows a remote attacker to execute arbitrary code by sending specially crafted packets containing the TXSTATUSSTARTPACKET and TXSTATUSDEVICEOWNS fields...

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...

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...

Null pointer dereference

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...
