OpenBSD Information for VU#803539
Multiple vendors' Domain Name System (DNS) stub resolvers vulnerable to buffer overflows
[T]he resolver libraries in question got copied far and wide. They used to have a hell of a lot of bugs in them.
Now might be a good time for people to compare each others' libraries to each other. I would urge them to compare against the OpenBSD ones, where we've spent a lot of time on, but of course we still missed this. But perhaps people can then share some around. Not everyone is going to move to the bind9 stuff, since it is very different.
The vendor has not provided us with any further information regarding this vulnerability.
