sssd (2.2.3-3ubuntu0.7) focal-security; urgency=medium

  * SECURITY UPDATE: shell command injection in sssctl comment
    - debian/patches/CVE-2021-3621.patch: replace system() with execvp() to
      avoid execution of user supplied command in
      src/tools/sssctl/sssctl.c, src/tools/sssctl/sssctl.h,
      src/tools/sssctl/sssctl_data.c, src/tools/sssctl/sssctl_logs.c.
    - CVE-2021-3621

sssd (2.2.3-3ubuntu0.6) focal; urgency=medium

  * debian/patches/fix-gpo-MS-ADTS-compliance.patch:
    - Backport several upstream patches from 2.3.x and 2.4.x in ad_gpo
      namespaces. This makes it compliant with MS ADTS spec, which allows
      gpos to be downloaded on user login. (LP: #1933116)

sssd (2.2.3-3ubuntu0.5) focal-proposed; urgency=medium

  * SRU: LP: #1931074: Fix tests to also pass with Python 3.8.10.

  [ Marco Trevisan ]
  * debian/control:
    - Add missing (test) dependencies as per libcrypto usage (LP: #1905790)
    - Update Maintainer to Ubuntu devs
  * debian/rules: Compile using libcrypto as crypto backend (LP: #1905790)
  * debian/nss-database-pem-exporter: Add to sssd-common and run on postinst.
    When upgrading from previous versions (that were compiled using the NSS
    crypto backend) we need to migrate the trusted CA certificates that the
    user may have added to the SSSD's NSS system database (that defaults to
    To do this, and not to introduce a new dependency on libnss3-tools
    (which is not shipped by default, other than making the parsing not
    working in some scenarios) I've added a small C tool that we compile and
    install as part of the sssd-common package which is able to get all the
    trusted CA certificates for a NSS database and export them in PEM
    The nss-database-pem-exporter is then used in the postinst script where
    we now:
     1. Read the SSSD settings
     2. Convert all the certificates in the configured NSS databases
     3. Store them all, appending them to the (new) default location
     4. Disables the configured locations if pointing to NSS dbs (needed or
        we'll leave the configuration with broken values).
    At this point nss-database-pem-exporter is then the only binary in the
    package that still depends on NSS libraries. (LP: #1905790)
  * debian/patches:
    - Get libsofthsm2 from right path for each architecture, this is now used
      for real (wasn't before) to test p11k components with libcrypto and
      p11-kit, also avoids a test build failure on armhf (LP: #1905790)

  [ Valters Jansons ]
  * Avoid sending malformed SYSLOG_IDENTIFIER to journald (LP: #1908065):
    - d/rules: Set --with-syslog=journald in override_dh_auto_configure.
    - d/p/lp-1908065-01-debug_prg_name-format.patch:
      Upstream patch to clean up program names.
    - d/p/lp-1908065-02-syslog_identifier-format.patch:
      Upstream patch to include "sssd[]" identifier in program names.
    - d/p/lp-1908065-03-remove-syslog_identifier.patch:
      Upstream patch to remove custom SYSLOG_IDENTIFIER from Journald.

sssd (2.2.3-3ubuntu0.3) focal; urgency=medium

  * d/apparmor-profile: Update profile. (LP: #1910611)
    - Extend read permissions to /etc/sssd/** and /etc/gss/**.
    - Add read/execute permission to /usr/libexec/sssd/*.

sssd (2.2.3-3ubuntu0.2) focal; urgency=medium

  * d/p/0003-Only-start-sssd.service-if-there-s-a-configuration-f.patch:
    Upstream patch to make sssd.service only able to start when there
    is a configuration file present.  (LP: #1900642)
