April BIND security release

2017-04-13 - News - Tony Finch

Yesterday evening there was a BIND security release fixing three vulnerabilities.

The most serious one is CVE-2017-3137 which can crash recursive servers. (It is related to the previous DNAME/CNAME RRset ordering bugs which led to security releases in January and November.)

The other vulnerabilities are in DNS64 support (which I don't think any of us use) and in the rndc control channel (which is mainly a worry if you have opened up read-only access in BIND 9.11).

More details on the bind-announce list, https://lists.isc.org/pipermail/bind-announce/2017-April/thread.html

I have patched the central DNS servers and the ppsw-specific resolvers.
