Security update for xen SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2017:1080-1 Final 1 1 2017-04-20T13:47:19Z current 2017-04-20T13:47:19Z 2017-04-20T13:47:19Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for xen 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-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-2017-6414: 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-2017-2633: 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). - 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). These non-security issues were fixed: - bsc#1022555: Timeout in 'execution of /etc/xen/scripts/block add' - bsc#1029827: Forward port xenstored The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
