Synopsis
The remote Mandriva Linux host is missing one or more security updates.
Description
Updated qemu packages fix security vulnerabilities :
A denial of service flaw was found in the way QEMU handled malformed Physical Region Descriptor Table (PRDT) data sent to the host's IDE and/or AHCI controller emulation. A privileged guest user could use this flaw to crash the system (rhbz#1204919).
It was found that the QEMU's websocket frame decoder processed incoming frames without limiting resources used to process the header and the payload. An attacker able to access a guest's VNC console could use this flaw to trigger a denial of service on the host by exhausting all available memory and CPU (CVE-2015-1779).
Solution
Update the affected qemu and / or qemu-img packages.
