Fedora 24: qemu Security Update 2017-62ac1230f7
Summary
QEMU is a generic and open source processor emulator which achieves a good
emulation speed by using dynamic translation. QEMU has two operating modes:
* Full system emulation. In this mode, QEMU emulates a full system (for
example a PC), including a processor and various peripherials. It can be
used to launch different Operating Systems without rebooting the PC or
to debug system code.
* User mode emulation. In this mode, QEMU can launch Linux processes compiled
for one CPU on another CPU.
As QEMU requires no host kernel patches to run, it is safe and easy to use.
Update Information:
* CVE-2017-5525: audio: memory leakage in ac97 (bz #1414110) * CVE-2017-5526: audio: memory leakage in es1370 (bz #1414210) * CVE-2016-10155 watchdog: memory leakage in i6300esb (bz #1415200) * CVE-2017-5552: virtio-gpu-3d: memory leakage (bz #1415283) * CVE-2017-5667: sd: sdhci OOB access during multi block transfer (bz #1417560) * CVE-2017-5857: virtio-gpu-3d: host memory leakage in virgl_cmd_resource_unref (bz #1418383) * CVE-2017-5856: scsi: megasas: memory leakage (bz #1418344) * CVE-2017-5898: usb: integer overflow in emulated_apdu_from_guest (bz #1419700) * CVE-2017-5987: sd: infinite loop issue in multi block transfers (bz #1422001) * CVE-2017-6505: usb: an infinite loop issue in ohci_service_ed_list (bz #1429434) * CVE-2017-2615: cirrus: oob access while doing bitblt copy backward (bz #1418206) * CVE-2017-2620: cirrus: potential arbitrary code execution (bz #1425419)
