Several vulnerabilities were discovered in qemu-kvm, a full virtualization solution on x86 hardware.

  • CVE-2015-5165 Donghai Zhu discovered that the QEMU model of the RTL8139 network card did not sufficiently validate inputs in the C+ mode offload emulation, allowing a malicious guest to read uninitialized memory from the QEMU process’s heap.

  • CVE-2015-5745 A buffer overflow vulnerability was discovered in the way QEMU handles the virtio-serial device. A malicious guest could use this flaw to mount a denial of service (QEMU process crash).
