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 SLE 15 (fate#324200).

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)
