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.
Can we stabilize 2.13? Please also take a look at bug 386327 before deciding.
glibc-2.13 is stable now
Thanks. Already on GLSA request.
