Summary

Security update for xen

Details

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 CIRRUSBLTMODEMEMSYSSRC mode the bitblit copy routine cirrusbitbltcputovideo 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 'ehciinittransfer'. 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 'mcffecreceive'. 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
