Access Restriction Bypass Affecting glibc package, versions <2.13-16

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

locale/programs/locale.c in locale in the GNU C Library (aka glibc or libc6) before 2.13 does not quote its output, which might allow local users to gain privileges via a crafted localization environment variable, in conjunction with a program that executes a script that uses the eval function.
