   An update that solves 8 vulnerabilities and has two fixes
   is now available.

Description:

   This update for qemu to version 2.9.1 fixes several issues.

   It also announces that the qed storage format will be no longer supported
   in Leap 15.0.

   These security issues were fixed:

   - CVE-2017-15268: Qemu allowed remote attackers to cause a memory leak by
     triggering slow data-channel read operations, related to
     io/channel-websock.c (bsc#1062942)
   - CVE-2017-15289: The mode4and5 write functions allowed local OS guest
     privileged users to cause a denial of service (out-of-bounds write
     access and Qemu process crash) via vectors related to dst calculation
     (bsc#1063122)
   - CVE-2017-15038: Race condition in the v9fs_xattrwalk function local
     guest OS users to obtain sensitive information from host heap memory via
     vectors related to reading extended attributes (bsc#1062069)
   - CVE-2017-10911: The make_response function in the Linux kernel allowed
     guest OS users to obtain sensitive information from host OS (or other
     guest OS) kernel memory by leveraging the copying of uninitialized
     padding fields in Xen block-interface response structures (bsc#1057378)
   - CVE-2017-12809: The IDE disk and CD/DVD-ROM Emulator support allowed
     local guest OS privileged users to cause a denial of service (NULL
     pointer dereference and QEMU process crash) by flushing an empty CDROM
     device drive (bsc#1054724)
   - CVE-2017-14167: Integer overflow in the load_multiboot function allowed
     local guest OS users to execute arbitrary code on the host via crafted
     multiboot header address values, which trigger an out-of-bounds write
     (bsc#1057585)
   - CVE-2017-13672: The VGA display emulator support allowed local guest OS
     privileged users to cause a denial of service (out-of-bounds read and
     QEMU process crash) via vectors involving display update (bsc#1056334)
   - CVE-2017-13711: Use-after-free vulnerability allowed attackers to cause
     a denial of service (QEMU instance crash) by leveraging failure to
     properly clear ifq_so from pending packets (bsc#1056291).

   These non-security issues were fixed:

   - Fixed not being able to build from rpm sources due to undefined macro
     (bsc#1057966)
   - Fiedx package build failure against new glibc (bsc#1055587)

   This update was imported from the SUSE:SLE-12-SP3:Update update project.
