Mandriva Linux Security Advisory 2015-061
Posted Mar 16, 2015
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2015-061 - Sibiao Luo discovered that QEMU incorrectly handled device hot-unplugging. A local user could possibly use this flaw to cause a denial of service. Michael S. Tsirkin discovered that QEMU incorrectly handled vmxnet3 devices. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. Multiple integer overflow, input validation, logic error, and buffer overflow flaws were discovered in various QEMU block drivers. An attacker able to modify a disk image file loaded by a guest could use these flaws to crash the guest, or corrupt QEMU process memory on the host, potentially resulting in arbitrary code execution on the host with the privileges of the QEMU process. Various other issues have also been addressed.
