Fedora 29: Critical QEMU Advisory for Multiple Security Issues

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.

* Fix cpu model crash on AMD hosts (bz #1640140) * CVE-2018-15746: seccomp

blacklist is not applied to all threads (bz #1618357) * Fix assertion in

address_space_stw_le_cached (bz #1644728) * CVE-2018-10839: ne2000: fix possible

out of bound access (bz #1636429) * CVE-2018-17958: rtl8139: fix possible out of

bound access (bz #1636729) * CVE-2018-17962: pcnet: fix possible buffer overflow

(bz #1636775) * CVE-2018-17963: net: ignore packet size greater than INT_MAX (bz

#1636782) * CVE-2018-18849: lsi53c895a: OOB msg buffer access leads to DoS (bz
