An update that solves 13 vulnerabilities and has four fixes
is now available.

Description:


This update for qemu fixes several issues.

These security issues were fixed:

- 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-2016-9776: The ColdFire Fast Ethernet Controller emulator support
was vulnerable to an infinite loop issue while receiving packets in
'mcf_fec_receive'. A privileged user/process inside guest could
have
used this issue to crash the Qemu process on the host leading to DoS
(bsc#1013285)
- CVE-2016-9911: The USB EHCI Emulation support was vulnerable to a memory
leakage issue while processing packet data in
'ehci_init_transfer'. A
guest user/process could have used this issue to leak host memory,
resulting in DoS for the host (bsc#1014111)
- CVE-2016-9907: The USB redirector usb-guest support was vulnerable to a
memory leakage flaw when destroying the USB redirector in
'usbredir_handle_destroy'. A guest user/process could have used
this
issue to leak host memory, resulting in DoS for a host (bsc#1014109)
- 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-2016-10155: 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-2017-5526: 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 post script for qemu-guest-agent rpm to actually activate the guest
agent at rpm install time
- Fixed various inaccuracies in cirrus vga device emulation
- Fixed cause of infrequent migration failures from bad virtio device
state (bsc#1020928)
- Fixed virtio interface failure (bsc#1015048)
- Fixed graphical update errors introduced by previous security fix
(bsc#1016779)
- Fixed uint64 property parsing and add regression tests (bsc#937125)
