    CVE-2015-1779

    Summary: Updated qemu packages fix security vulnerabilities

    Details: 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).
