Mandriva Linux Security Advisory : qemu (MDVSA-2015:210)

high Nessus Plugin ID 83102

Language:

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.
