This update fixes a minor security vulnerability (
LD_PREFER_MAP_32BIT_EXEC not ignored in setuid binaries and addresses are long-standing bug where missing shared objects could cause crashes due to incorrectly handled
dlopen failures (#1395758). The latter fix also causes lazy binding failures in ELF constructors and destructors to result in process termination (the same effect that lazy binding failures have in other contexts), rather than leaving the process in an inconsistent state. Furthermore, various issues in the
utmpx subsystem have been addressed.
This update also includes various minor fixes from the glibc 2.30 upstream stable release branch.
