- CVE-2017-14492: heap based overflow. [bsc#1060355]
- CVE-2017-14493: stack based overflow. [bsc#1060360]
- CVE-2017-14494: DHCP - info leak. [bsc#1060361]
- CVE-2017-14495: DNS - OOM DoS. [bsc#1060362]
- CVE-2017-14496: DNS - DoS Integer underflow. [bsc#1060364]
- Prevent a man-in-the-middle attack (bsc#972164, fate#321175).
Furthermore, the following issues have been fixed:
- Fix DHCP relaying, broken in 2.76 and 2.77.
- Update to version 2.78 (fate#321175, fate#322030, bsc#1035227).
- Fix PXE booting for UEFI architectures (fate#322030).
- Drop PrivateDevices=yes which breaks logging (bsc#902511, bsc#904537)
- Build with support for DNSSEC (fate#318323, bsc#908137).
Please note that this update brings a (small) potential incompatibility in the
handling of 'basename' in --pxe-service. Please read the CHANGELOG and the
