Assunto: [DNG] bind9 updates broke, needed second aptitude update
Hi,

I found on a couple of systems that an upgrade of bind9 caused it to fail to start.

The fix [for me] was to do a second update/upgrade as well as making sure that /etc/resolv.conf had a nameserver it could
find and use. I must have just been caught after doing the update to the faulty version just before the fix come through.

This was on two systems still running ascii


bind9 versions:
   Pre-first update/upgrade
     1:9.10.3.dfsg.P4-12.3+deb9u10


   The versions for the two update/upgrades ...
     1:9.10.3.dfsg.P4-12.3+deb9u11
     1:9.10.3.dfsg.P4-12.3+deb9u12


Turns out that 1:9.10.3.dfsg.P4-12.3+deb9u11 was broken.


The changelog refers to this:\

    * Non-maintainer upload by the LTS team.
    * Fix CVE-2021-25220:
      When using forwarders, bogus NS records supplied by, or via, those
      forwarders may be cached and used by named if it needs to recurse for any

I expect a single update/upgrade should be fine now, but just in case this helps anyone else, it's on the mailing list now ;-)


Cheers
