  - CVE-2018-17963: Fixed qemu_deliver_packet_iov in     net/net.c that accepts packet sizes greater than     INT_MAX, which allows attackers to cause a denial of     service or possibly have unspecified other impact.
    (bsc#1111013)

  - CVE-2018-18849: Fixed an out of bounds memory access     issue that was found in the LSI53C895A SCSI Host Bus     Adapter emulation while writing a message in     lsi_do_msgin. It could occur during migration if the     'msg_len' field has an invalid value. A user/process     could use this flaw to crash the Qemu process resulting     in DoS (bsc#1114422).

Non-security issues fixed :
