update for xen fixes several issues.\n\nThese security issues were fixed:\n\n- CVE-2017-12135: Unbounded recursion in grant table code allowed a malicious\n  guest to crash the host or potentially escalate privileges/leak information\n  (XSA-226, bsc#1051787).\n- CVE-2017-12137: Incorrectly-aligned updates to pagetables allowed for\n  privilege escalation (XSA-227, bsc#1051788).\n- CVE-2017-11334: The address_space_write_continue function in exec.c allowed\n  local guest OS privileged users to cause a denial of service (out-of-bounds\n  access and guest instance crash) by leveraging use of qemu_map_ram_ptr to\n  access guest ram block area (bsc#1048920).\n- CVE-2017-11434: The dhcp_decode function in slirp/bootp.c allowed local guest\n  OS users to cause a denial of service (out-of-bounds read) via a crafted DHCP\n  options string (bsc#1049578).\n- CVE-2017-10806: Stack-based buffer overflow in hw/usb/redirect.c allowed\n  local guest OS users to cause a denial of service via vectors related to\n  logging debug messages (bsc#1047675).\n- CVE-2017-10664: qemu-nbd did not ignore SIGPIPE, which allowed remote\n  attackers to cause a denial of service (daemon crash) by disconnecting during \n  a server-to-client reply attempt (bsc#1046637).\n- CVE-2017-12855: Premature clearing of GTF_writing / GTF_reading lead to\n  potentially leaking sensitive information (XSA-230, bsc#1052686).\n- CVE-2017-14316: Missing bound check in function `alloc_heap_pages` for an\n  internal array allowed attackers using crafted hypercalls to execute\n  arbitrary code within Xen (XSA-231, bsc#1056278)\n- CVE-2017-14317: A race in cxenstored may have cause a double-free allowind for\n  DoS of the xenstored daemon (XSA-233, bsc#1056281).\n- CVE-2017-14319: An error while handling grant mappings allowed malicious or\n  buggy x86 PV guest to escalate its privileges or crash the hypervisor (XSA-234,\n  bsc#1056282).\n\nThese non-security issues were fixed:\n\n- bsc#1002573: Optimized LVM functions in block-dmmd block-dmmd\n- bsc#1032598: Prevent removal of NVME devices\n- bsc#1037413: Support for newer intel cpu's, mwait-idle driver and skylake\n","id":"SUSE-SU-2017:2541-1","modified":"2017-09-21T15:30:58Z","published":"2017-09-21T15:30:58Z","references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2017/suse-su-20172541-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1002573"},{"type":"REPORT","url":"https://bugzilla.suse.com/1027519"},{"type":"REPORT","url":"https://bugzilla.suse.com/1032598"},{"type":"REPORT","url":"https://bugzilla.suse.com/1037413"},{"type":"REPORT","url":"https://bugzilla.suse.com/1046637"},{"type":"REPORT","url":"https://bugzilla.suse.com/1047675"},{"type":"REPORT","url":"https://bugzilla.suse.com/1048920"},{"type":"REPORT","url":"https://bugzilla.suse.com/1049578"},{"type":"REPORT","url":"https://bugzilla.suse.com/1051787"},{"type":"REPORT","url":"https://bugzilla.suse.com/1051788"},{"type":"REPORT","url":"https://bugzilla.suse.com/1052686"},{"type":"REPORT","url":"https://bugzilla.suse.com/1056278"},{"type":"REPORT","url":"https://bugzilla.suse.com/1056281"},{"type":"REPORT","url":"https://bugzilla.suse.com/1056282"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-10664"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-10806"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-11334"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-11434"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-12135"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-12137"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-12855"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-14316"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-14317"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-14319"}],"related":["CVE-2017-10664","CVE-2017-10806","CVE-2017-11334","CVE-2017-11434","CVE-2017-12135","CVE-2017-12137","CVE-2017-12855","CVE-2017-14316","CVE-2017-14317","CVE-2017-14319"],"summary":"Security
