An update that solves 12 vulnerabilities and has one errata
is now available.
Description:
This update for xen fixes several issues.
These security issues were fixed:
- 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-2017-2615: 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-2014-8106: A heap-based buffer overflow in the Cirrus VGA emulator
allowed local guest users to execute arbitrary code via vectors related
to blit regions (bsc#907805)
- 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-2016-10013: Xen allowed local 64-bit x86 HVM guest OS users to gain
privileges by leveraging mishandling of SYSCALL singlestep during
emulation (bsc#1016340).
- CVE-2016-9932: CMPXCHG8B emulation on x86 systems allowed local HVM
guest OS users to obtain sensitive information from host stack memory
via a "supposedly-ignored" operand size prefix (bsc#1012651).
- 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)
- 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-2016-10024: Xen allowed local x86 PV guest OS kernel administrators
to cause a denial of service (host hang or crash) by modifying the
instruction stream asynchronously while performing certain kernel
operations (bsc#1014298)
This non-security issue was fixed:
- bsc#1002496: Added support for reloading clvm in block-dmmd block-dmmd
