This issue was patched in RHSA-2020:1828.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-langpack-tt package and not the glibc-langpack-tt package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.
