Details

This update for xen to version 4.7.3 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-2017-12136: Race conditions with maptrack free list handling allows a malicious guest administrator to crash the host or escalate their privilege to that of the host (XSA-228, bsc#1051789).
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-2017-12855: Premature clearing of GTFwriting / GTFreading lead to potentially leaking sensitive information (XSA-230 CVE-2017-12855).
