Greetings.
This morning one of our BIND daemons crashed. The following messages were
logged in named.run at the time:
07-Dec-2022 11:58:37.097 general: critical: netmgr.c:687:
REQUIRE((__builtin_expect(!!((sock) != ((void *)0)), 1) &&
__builtin_expect(!!(((const isc__magic_t *)(sock))->magic
To me, the next step is to get your instance of BIND somewhat up to date.
I'm not a "gotta be on the bleeding edge" kinda guy, but running a
version released in first quarter of 2020 is old even by my standards.
Is there some business reason to keep running a +2 year old version of BIND?

I see https://gitlab.isc.org/isc-projects/bind9/-/issues/3020 and
https://gitlab.isc.org/isc-projects/bind9/-/merge_requests/5998 which might
help
I did not see a CVE but only did a quick search

Ubuntu 20.04.5 is LTS and BIND 9.16 is the current stable ESV release, so
they’re both still fully supported (and fully patched).
Thanks,

No, your release is not patched.
Add the ISC PPA repo and install the latest ESV. ISC PPA packaged are
packaged by the same maintainers.

According to the Ubuntu maintainers, the bind9 package on our server
(1:9.16.1-0ubuntu2.11) is fully patched for all the BIND 9 CVE's including the
latest batch of 6 released on 2022-09-21 (CVE-2022-38178, CVE-2022-38177,
CVE-2022-3080, CVE-2022-2906, CVE-2022-2881, and CVE-2022-2795).

It looks like that issue was occurring in a different part of the netmgr code
and was fixed 8 months ago.

I see
https://gitlab.
As the package maintained by the Ubuntu team are “no longer” the source from
ISC (but highly modified patches onto an old 9.16.1 source tree), I’d suggest
following up with the Ubuntu maintainers of the package, as it’s likely their
back-porting of security patches from much more recent releases
Hello,
I see logs like [ECS 192.168.2.0/24/0] but I don't understand what is the last
/0 part.
Where can I get an explanation ?

Is that the entire log message or just part of it? Is this a
recursive or authoritative name server? What version of bind?
Logging is covered in the manual though I don't really see a
comprehensive explanation of message format (maybe it's there and I'm

Found the answer in the manual:

In fact, it’s as far from being “fully patched” as possible. Not all bugs are security bugs and not all crashes are security bugs.Ubuntu is pushing a version that has received most refactoring in the networking code in the recent history.The “we don’t update upstream version” policy works well only
When you say “ISC packages”, are you referring to the packages in the
ppa:isc/bind repository on launchpad?

Somewhat OT, but this applies to more or less all software which you
