[Bug 1258003] [NEW] DiG crashes on +nssearch with +tcp [Outdated in Ubuntu repo]
Public bug reported: Precursor: 'DiG' is provided in the package "bind9", and the version in DiG is the same version of bind9. Whilst running 'DiG', with +ssearch, AND +tcp, on the DiG version that is available in the repo's("DiG 9.8.1-P1"), the program segfaults with a core dump. Example: 13:13:14 (toil@laptop) ~ $ dig -v DiG 9.8.1-P1 13:13:37 (toil@laptop) ~ $ dig +time=3 +nssearch +tcp internot.info socket.c:2535: REQUIRE(socketp != ((void *)0) && *socketp == ((void *)0)) failed, back trace #0 0x4f877b in ?? #1 0x4f86c4 in ?? #2 0x52b062 in ?? #3 0xfd03ef in ?? #4 0xfd07c3 in ?? #5 0x51b9ac in ?? #6 0x7cdd4c in ?? #7 0x1ffbae in ?? Aborted (core dumped) It's strange that it gives a back trace, but that's irrelevant anyways. Although I'm unsure of which version exactly it's fixed in, but it doesn't work in "DiG 9.10.0a1". It also seems to be patched in "DiG 9.8.4-P2", but that probably isn't useful (due to the P2)..

Erm, it looks like /usr/bin/dig is actually provided by `dnsutils', not bind9.

Just an update on this: It is patched in Ubuntu 14.04.1. I have identified another bug in DiG which is yet to be patched in any versions of bind(I only just reported it now), which affects those that use ipv6. megamansec@megamansec:~$ lsb_release -a No LSB modules are available.
