This update for ovmf fixes the following issues :
Security issues fixed :
CVE-2018-12180: Fixed a buffer overflow in BlockIo service, which could lead to memory read/write overrun (bsc#1127820).
CVE-2018-12178: Fixed an improper DNS check upon receiving a new DNS packet (bsc#1127821).
CVE-2018-3630: Fixed a logic error in FV parsing which could allow a local attacker to bypass the chain of trust checks (bsc#1127822).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
