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.
