It could occur while processing network packets\nunder RTL8139 controller's C+ mode of operation. A guest user could use this\nflaw to read uninitialised Qemu heap memory up to 65K bytes (CVE-2015-5165).\n\nQinghao Tang and Mr. Zuozhi discovered that QEMU incorrectly handled memory in\nthe VNC display driver. A malicious guest could use this issue to cause a\ndenial of service, or possibly execute arbitrary code on the host as the user\nrunning the QEMU process (CVE-2015-5225). - Mageia 5 only\n\nQemu emulator built with the e1000 NIC emulation support is vulnerable to an\ninfinite loop issue. It could occur while processing transmit descriptor data\nwhen sending a network packet.
