qemu was updated to fix several issues. These security issues were fixed :

  - CVE-2016-9102: Memory leak in the v9fs_xattrcreate     function in hw/9pfs/9p.c in allowed local guest OS     administrators to cause a denial of service (memory     consumption and QEMU process crash) via a large number     of Txattrcreate messages with the same fid number     (bsc#1014256).

  - CVE-2016-9103: The v9fs_xattrcreate function in     hw/9pfs/9p.c in allowed local guest OS administrators to     obtain sensitive host heap memory information by reading     xattribute values writing to them (bsc#1007454).

  - CVE-2016-9381: Improper processing of shared rings     allowing guest administrators take over the qemu     process, elevating their privilege to that of the qemu     process (bsc#1009109)

  - CVE-2016-9776: The ColdFire Fast Ethernet Controller     emulator support was vulnerable to an infinite loop     issue while receiving packets in 'mcf_fec_receive'.
