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)
