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

Description:


This update for xen fixes several issues.

These security issues were fixed:

- CVE-2017-5973: A infinite loop while doing control transfer in
xhci_kick_epctx allowed privileged user inside the guest to crash the
host process resulting in DoS (bsc#1025188).
- 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#1024183).
- 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#1024834)
- 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#1024186).
- 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#1024307).
- 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)
- A malicious guest could have, by frequently rebooting over extended
periods of time, run the host system out of memory, resulting in a
Denial of Service (DoS) (bsc#1022871)
- CVE-2017-5579: The 16550A UART serial device emulation support 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#1022627).
- 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#1014490)
- 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#1014507)
- 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#1015169)
- 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#1015169)
- CVE-2016-9101: A memory leak in hw/net/eepro100.c allowed local guest OS
administrators to cause a denial of service (memory consumption and QEMU
process crash) by repeatedly unplugging an i8255x (PRO100) NIC device
(bsc#1013668).
- 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#1013657)

These non-security issues were fixed:

- bsc#1000195: Prevent panic on CPU0 while booting on SLES 11 SP3
- bsc#1002496: Added support for reloading clvm in block-dmmd block-dmmd
