______________________________________________________________________________

An update that solves 7 vulnerabilities and has four fixes
is now available.

Description:

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 GTF_writing / GTF_reading lead to
potentially leaking sensitive information (XSA-230 CVE-2017-12855).

These non-security issues were fixed:

– bsc#1055695: XEN: 11SP4 and 12SP3 HVM guests can not be restored after
the save using xl stack
– bsc#1035231: Migration of HVM domU did not use superpages on destination
dom0
– bsc#1002573: Optimized LVM functions in block-dmmd block-dmmd
– bsc#1037840: Xen-detect always showed HVM for PV guests
