ap/sudo-1.9.15-x86_64-1.txz:  Upgraded.
  The sudoers plugin has been modified to make it more resilient to ROWHAMMER
  attacks on authentication and policy matching.
  The sudoers plugin now constructs the user time stamp file path name using
  the user-ID instead of the user name. This avoids a potential problem with
  user names that contain a path separator ('/') being interpreted as part of
  the path name.

  (* Security fix *)
ap/vim-9.0.2092-x86_64-1.txz:  Upgraded.
l/libuv-1.47.0-x86_64-1.txz:  Upgraded.
l/xapian-core-1.4.24-x86_64-1.txz:  Upgraded.
n/bind-9.18.19-x86_64-2.txz:  Rebuilt.
  Don't go automatically chowning files in /var/named, since some users may
  have special requirements. But in case anyone finds that behavior useful,
  you may set NAMED_CHOWN=YES in /etc/default/named to turn it back on.
  Unless anyone has a good objection to it, this change is considered pending
  for the next BIND upgrades in -stable.
  Thanks to Mig21.

# Start/stop/restart the BIND name server daemon (named).
# Start BIND. By default this will run with user "named". If you'd like to
# change this or other options, see: /etc/default/named
# You might also consider running BIND in a "chroot jail",
# a discussion of which may be found in
# /usr/doc/Linux-HOWTOs/Chroot-BIND-HOWTO.
# One last note: rndc has a lot of other nice features that it is not
# within the scope of this start/stop/restart script to support.
# For more details, see "man rndc" or just type "rndc" to see the options.
