freed by the caller, leading to a denial of service (application crash)
or possibly unspecified other impact (CVE-2021-33574).

Other fixes in this update:
- fix triggers so ldconfig is always run on both installing and
 uninstalling libs (mga#28797)
- Fix SXID_ERASE behavior in setuid programs [BZ#27471]");
