I Debians fejlsporingssystem: Fejl 323789.
I Mitres CVE-ordbog: CVE-2005-2963.

Yderligere oplysninger:

En sårbarhed i mod_auth_shadow, et Apache-modul der lader brugere HTTP-autentificere mod /etc/shadow, er opdaget. Modulet kører alle steder hvor kommandoen 'require group' anvendes, hvilket omgik adgangsbegrænsninger der kontrolleres af en anden autorisationsmekanisme, såsom filen AuthGroupFile, hvis brugernavnet var anført i password- og gshadow-filerne i den rette gruppe, og den angivne adgangskode var magen til den i shadow-filen.

Denne opdatering kræver eksplicit "AuthShadow on"-kommandon, hvis webstedets autentifikation skal kontrolleres mod /etc/shadow.

I den gamle stabile distribution (woody) er dette problem rettet i version 1.3-3.1woody.2.

I den stabile distribution (sarge) er dette problem rettet i version 1.4-1sarge1.

I den ustabile distribution (sid) er dette problem rettet i version 1.4-2.

Vi anbefaler at du opgraderer din libapache-mod-auth-shadow-pakke.
