a/util-linux-2.35.1-x86_64-1.txz:  Upgraded.
a/zerofree-1.1.1-x86_64-1.txz:  Added.
  Also queued up for the next installer build. Thanks to bifferos.
ap/sudo-1.8.31-x86_64-1.txz:  Upgraded.
  This update fixes a security issue:
  In Sudo before 1.8.31, if pwfeedback is enabled in /etc/sudoers, users can
  trigger a stack-based buffer overflow in the privileged sudo process.
  (pwfeedback is a default setting in some Linux distributions; however, it
  is not the default for upstream or in Slackware, and would exist only if
  enabled by an administrator.) The attacker needs to deliver a long string
  to the stdin of getln() in tgetpass.c.
  For more information, see:
    https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-18634
  (* Security fix *)
n/NetworkManager-1.22.6-x86_64-1.txz:  Upgraded.
n/openldap-client-2.4.49-x86_64-1.txz:  Upgraded.
xfce/Thunar-1.8.11-x86_64-1.txz:  Removed.
xfce/thunar-1.8.12-x86_64-1.txz:  Added.
  Changed package name from "Thunar" to "thunar" to follow upstream's naming.
