Mandriva Linux Security Advisory 2015-210

Mandriva Linux Security Advisory 2015-210

Mandriva Linux Security Advisory 2015-210 - A denial of service flaw was found in the way QEMU handled malformed Physical Region Descriptor Table data sent to the host's IDE and/or AHCI controller emulation. A privileged guest user could use this flaw to crash the system. 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.

Package : qemu
Date : April 27, 2015
Affected: Business Server 1.0, Business Server 2.0
_______________________________________________________________________

Problem 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).
