Bitcoin Core 0.14.2 has been released with a security fix for
users who manually enable the UPnP option. Please note: UPnP has been
disabled by default since Bitcoin Core 0.10.3; you only need this
fix if you start Bitcoin Core with the -upnp option on the command
line or in your configuration file.
If you use -upnp, it is recommended that you upgrade to Bitcoin Core
0.14.2 as soon as possible. The security issue (miniupnp
CVE-2017-8798) allows remote attackers (within the Local Area
Network, LAN) to cause a denial of service or possibly have unspecified
other impact.
This release also includes a few other bug fixes, all minor. Please see
the release notes for details. To download, please visit the
download page or the files directory.
