Summary: LD_POINTER_GUARD is not ignored for privileged
binaries
Product: glibc
Version: unspecified
Status: NEW
Severity: normal

>From https://sourceware.org/ml/libc-alpha/2015-09/msg00164.html

The issue is that the LD_POINTER_GUARD in the
environment is not sanitized allowing local attackers easily to bypass
the pointer guarding protection on set-user-ID and set-group-ID
programs.
