An update that solves two vulnerabilities and has one security fix can now be installed.

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)
