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
