   An update that solves two vulnerabilities and has one
   errata is now available.

Description:

   This update for multipath-tools fixes the following issues:

   - CVE-2022-41973: Fixed a symlink attack in multipathd. (bsc#1202739)
   - CVE-2022-41974: Fixed an authorization bypass issue in multipathd.
     (bsc#1202739)
   - Avoid linking to libreadline to avoid licensing issue (bsc#1202616)
   - multipathd: add "force_reconfigure" option (bsc#1189551) The command
     "multipathd -kreconfigure" changes behavior: instead
     of reloading every map, it checks map configuration and reloads
     only modified maps. This speeds up the reconfigure operation
      substantially. The old behavior can be reinstated by setting
      "force_reconfigure yes" in multipath.conf (not recommended). Note:
      "force_reconfigure yes" is not supported in SLE15-SP4 and beyond, which
      provide the command "multipathd -k'reconfigure all'"
   - multipathd: avoid stalled clients during reconfigure (bsc#1189551)
   - multipathd: handle client disconnect correctly (bsc#1189551)
