An update that solves 5 vulnerabilities and has four fixes

is now available.

 

Description:

 

 

This update for xen fixes the following issues:

 

These security issues were fixed:

 

- CVE-2017-7228: Broken check in memory_exchange() permited PV guest

breakout (bsc#1030442).

- XSA-206: Unprivileged guests issuing writes to xenstore were able to

stall progress of the control domain or driver domain, possibly leading

to a Denial of Service (DoS) of the entire host (bsc#1030144).

- CVE-2016-9603: A privileged user within the guest VM can cause a heap

overflow in the device model process, potentially escalating their

privileges to that of the device model process (bsc#1028655).

- CVE-2017-6414: Memory leak in the vcard_apdu_new function in card_7816.c

in libcacard allowed local guest OS users to cause a denial of service

(host memory consumption) via vectors related to allocating a new APDU

object (bsc#1027570).

- CVE-2017-6505: The ohci_service_ed_list function in hw/usb/hcd-ohci.c

allowed local guest OS users to cause a denial of service (infinite

loop) via vectors involving the number of link endpoint list descriptors

(bsc#1028235).

- CVE-2017-2633: The VNC display driver support was vulnerable to an

out-of-bounds memory access issue. A user/process inside guest could use

this flaw to cause DoS (bsc#1026636).

 

These non-security issues were fixed:

 

- bsc#1022555: Timeout in "execution of /etc/xen/scripts/block add"

- bsc#1029827: Forward port xenstored
