Affected Products:
  • SUSE Linux Enterprise Micro 5.2
  • SUSE Linux Enterprise Micro for Rancher 5.2

An update that solves two vulnerabilities, contains two features and has two security fixes can now be installed.

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)
