Dear oldstable release team,
I would like to update the eglibc package in wheezy to fix the known
security issues for which there is a patch available. The changes match
the security bugs opened by the security team, their severity wasn't
high enough to warrant a DSA.
You'll find the corresponding diff against the current version in
wheezy below.
Thanks,
Aurelien
