   An update that solves two vulnerabilities, contains two
   features and has two fixes is now available.

Description:

   This security update for libeconf, shadow and util-linux fix the following
   issues:

   libeconf:

   - Add libeconf to SLE-Module-Basesystem_15-SP3 because needed by
     'util-linux' and 'shadow' to fix autoyast handling of security related
     parameters (bsc#1192954, jsc#SLE-23384, jsc#SLE-23402)

   Issues fixed in libeconf:
   - Reading numbers with different bases (e.g. oktal) (bsc#1193632) (#157)
   - Fixed different issues while writing string values to file.
   - Writing comments to file too.
   - Fixed crash while merging values.
   - Added econftool cat option (#146)
   - new API call: econf_readDirsHistory (showing ALL locations)
   - new API call: econf_getPath (absolute path of the configuration file)
   - Man pages libeconf.3 and econftool.8.
   - Handling multiline strings.
   - Added libeconf_ext which returns more information like line_nr,
     comments, path of the configuration file,...
   - Econftool, an command line interface for handling configuration files.
   - Generating HTML API documentation with doxygen.
   - Improving error handling and semantic file check.
   - Joining entries with the same key to one single entry if env variable
     ECONF_JOIN_SAME_ENTRIES has been set.

   shadow:

   - The legacy code does not support /etc/login.defs.d used by YaST. Enable
     libeconf to read it (bsc#1192954, jsc#SLE-23384, jsc#SLE-23402)

   util-linux:

   - The legacy code does not support /etc/login.defs.d used by YaST. Enable
     libeconf to read it (bsc#1192954, jsc#SLE-23384, jsc#SLE-23402)
   - Allow use of larger values for start sector to prevent `blockdev
     --report` aborting (bsc#1188507)
   - Fixed `blockdev --report` using non-space characters as a field
     separator (bsc#1188507)
   - CVE-2021-3995: Fixed unauthorized unmount in util-linux's libmount.
     (bsc#1194976)
   - CVE-2021-3996: Fixed unauthorized unmount in util-linux's libmount.
     (bsc#1194976)
