Plus de précisions :

Ben Hawkes et Tavis Ormandy ont découvert que le chargeur dynamique de libc GNU permet à des utilisateurs locaux d'obtenir les droits du superutilisateur en utilisant une variable d'environnement LD_AUDIT contrefaite.

Pour la distribution stable (Lenny), ce problème a été corrigé dans la version 2.7-18lenny6.

Pour la prochaine distribution stable (Squeeze), ce problème a été corrigé dans la version 2.11.2-6+squeeze1 du paquet eglibc.
