Summary
[none]
Details

On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LDPREFERMAP32BITEXEC 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.
