SUSE SLED12 / SLES12 Security Update : qemu (SUSE-SU-2017:0625-1)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

This update for qemu fixes several issues. These security issues were
fixed :

- CVE-2017-5898: The CCID Card device emulator support was
vulnerable to an integer overflow flaw allowing a
privileged user to crash the Qemu process on the host
resulting in DoS (bsc#1023907).

- CVE-2017-5857: The Virtio GPU Device emulator support
was vulnerable to a host memory leakage issue allowing a
guest user to leak host memory resulting in DoS
(bsc#1023073).

- CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the
bitblit copy routine cirrus_bitblt_cputovideo failed to
check the memory region, allowing for an out-of-bounds
write that allows for privilege escalation (bsc#1024972)

- CVE-2017-2615: An error in the bitblt copy operation
could have allowed a malicious guest administrator to
cause an out of bounds memory access, possibly leading
to information disclosure or privilege escalation
(bsc#1023004)

- CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter
emulation support was vulnerable to a memory leakage
issue allowing a privileged user to leak host memory
resulting in DoS (bsc#1023053)

- CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support
was vulnerable to a divide by zero issue while copying
VGA data. A privileged user inside guest could have used
this flaw to crash the process instance on the host,
resulting in DoS (bsc#1014702)

- CVE-2016-9922: The Cirrus CLGD 54xx VGA Emulator support
was vulnerable to a divide by zero issue while copying
VGA data. A privileged user inside guest could have used
this flaw to crash the process instance on the host,
resulting in DoS (bsc#1014702)

- CVE-2016-10029: The Virtio GPU Device emulator support
was vulnerable to an OOB read issue allowing a guest
user to crash the Qemu process instance resulting in Dos
(bsc#1017081).

- CVE-2016-10028: The Virtio GPU Device emulator support
was vulnerable to an out of bounds memory access issue
allowing a guest user to crash the Qemu process instance
on a host, resulting in DoS (bsc#1017084).

- CVE-2016-10155: The virtual hardware watchdog
'wdt_i6300esb' was vulnerable to a memory leakage issue
allowing a privileged user to cause a DoS and/or
potentially crash the Qemu process on the host
(bsc#1021129)

- CVE-2017-5552: The Virtio GPU Device emulator support
was vulnerable to a memory leakage issue allowing a
guest user to leak host memory resulting in DoS
(bsc#1021195).

- CVE-2017-5578: The Virtio GPU Device emulator support
was vulnerable to a memory leakage issue allowing a
guest user to leak host memory resulting in DoS
(bsc#1021481).

- CVE-2017-5526: The ES1370 audio device emulation support
was vulnerable to a memory leakage issue allowing a
privileged user inside the guest to cause a DoS and/or
potentially crash the Qemu process on the host
(bsc#1020589).

- CVE-2017-5525: The ac97 audio device emulation support
was vulnerable to a memory leakage issue allowing a
privileged user inside the guest to cause a DoS and/or
potentially crash the Qemu process on the host
(bsc#1020491).

- CVE-2017-5667: The SDHCI device emulation support was
vulnerable to an OOB heap access issue allowing a
privileged user inside the guest to crash the Qemu
process resulting in DoS or potentially execute
arbitrary code with privileges of the Qemu process on
the host (bsc#1022541).

- CVE-2017-5898: The CCID Card device emulator support was
vulnerable to an integer overflow allowing a privileged
user inside the guest to crash the Qemu process
resulting in DoS (bnc#1023907) These non-security issues
were fixed :

- Fix name of s390x specific sysctl configuration file to
end with .conf (bsc#1026583)

- XHCI fixes (bsc#977027)

- Fixed rare race during s390x guest reboot

- Fixed various inaccuracies in cirrus vga device
emulation

- Fixed cause of infrequent migration failures from bad
virtio device state (bsc#1020928)

- Fixed graphical update errors introduced by previous
security fix (bsc#1016779)
