    Package        : debian-security-support
    Version        : 1:10+2023.13.12
    Debian Bug     : #982258, #1056606, #1053109.

    debian-security-support, the Debian security support coverage checker, has been
    updated in buster-security to mark the end of life of the following packages:

      * gnupg1: see #982258.
      * pluxml: removed from Debian. No upstream response to CVE.
      * tor: see https://lists.debian.org/debian-lts/2023/11/msg00019.html
        and #1056606.

    Additionally these packages are now marked with limited support:

      * samba support limited to non-AD DC uses cases: see #1053109 and
        https://lists.debian.org/debian-security-announce/2021/msg00201.html
      * webkit2gtk: see commit/0980414e8fc86d705ff9a7656c637af7b1170c6f

    For Debian 10 buster, this has been documented in version 1:10+2023.13.12.

    We recommend that you upgrade your debian-security-support packages.
