GCVE-VVD-MAGEIA-2021-308

The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been 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]
