Notes

Title of the patch
Security update for kvm
Description of the patch
This update for kvm fixes the following issues: Security issues fixed: - CVE-2015-7512: The receive packet size is now checked in the emulated pcnet driver, eliminating buffer overflow and potential security issue by malicious guest systems. (bsc#957162) - CVE-2015-8345: A infinite loop in processing command block list was fixed that could be exploit by malicious guest systems (bsc#956829). Other bugs fixed: - To assist users past the migration incompatibility discussed in bsc#950590 (restore migration compatibility with SLE11 SP3 and SLE12, at the unfortunate expense to prior SLE11 SP4 kvm release compatability when a virtio-net device is used), print a message which references the support document TID 7017048. See https://www.suse.com/support/kb/doc.php?id=7017048 - Fix cases of wrong clock values in kvmclock timekeeping (bsc#947164 and bsc#953187) - Enforce pxe rom sizes to ensure migration compatibility. (bsc#950590) - Fix kvm live migration fails between sles11 sp3 and sp4 (bsc#950590)
