The remote SUSE host is missing one or more security updates.
This update for xen fixes several issues. These security issues were fixed : - CVE-2017-12135: Unbounded recursion in grant table code allowed a malicious guest to crash the host or potentially escalate privileges/leak information (XSA-226, bsc#1051787). - CVE-2017-12137: Incorrectly-aligned updates to pagetables allowed for privilege escalation (XSA-227, bsc#1051788). - CVE-2017-11434: The dhcp_decode function in slirp/bootp.c allowed local guest OS users to cause a denial of service (out-of-bounds read) via a crafted DHCP options string (bsc#1049578). - CVE-2017-10664: qemu-nbd did not ignore SIGPIPE, which allowed remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt (bsc#1046637). - CVE-2017-11334: The address_space_write_continue function in exec.c allowed local guest OS privileged users to cause a denial of service (out-of-bounds access and guest instance crash) by leveraging use of qemu_map_ram_ptr to access guest ram block area (bsc#1048920). - CVE-2017-10806: Stack-based buffer overflow in hw/usb/redirect.c allowed local guest OS users to cause a denial of service via vectors related to logging debug messages (bsc#1047675). - bsc#1052686: Premature clearing of GTF_writing / GTF_reading lead to potentially leaking sensitive information (XSA-230). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
