Summary

Security update for xen

Details

This update for xen fixes several issues.

These security issues were fixed:

CVE-2017-2620: In CIRRUSBLTMODEMEMSYSSRC mode the bitblit copy routine cirrusbitbltcputovideo failed to check the memory region, allowing for an out-of-bounds write that allows for privilege escalation (bsc#1024834).
CVE-2017-2615: An error in the bitblt copy operation could have allowed a malicious guest administrator to cause an out of bounds memory access, possibly leading to information disclosure or privilege escalation (bsc#1023004).
A malicious guest could have, by frequently rebooting over extended periods of time, run the host system out of memory, resulting in a Denial of Service (DoS) (bsc#1022871)
CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support was vulnerable to a divide by zero issue while copying VGA data. A privileged user inside guest could have used this flaw to crash the process instance on the host, resulting in DoS (bsc#1015169

These non-security issues were fixed:

bsc#1000195: Prevent panic on CPU0 while booting on SLES 11 SP3
bsc#1002496: Added support for reloading clvm in block-dmmd block-dmmd
bsc#1005028: Fixed building Xen RPMs from Sources
