MGASA-2015-0149 - Updated qemu packages fix security vulnerabilities

Publication date: 15 Apr 2015
URL: http://advisories.mageia.org/MGASA-2015-0149.html
Type: security
Affected Mageia releases: 4
CVE: CVE-2015-1779

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).
