U radu programskog paketa krb5, distribuiranog s operacijskim sustavima Fedora 13 i 14, uočene su višestruke sigurnosne ranjivosti. Pojedine ranjivosti se javljaju u funkcijama "kg_accept_krb5" i "do_standalone", zbog dereferenciranja NULL pokazivača, pogreške u GSS-API biblioteci, itd. Udaljeni, zlonamjerni korisnici mogu ove ranjivosti iskoristiti za povećanje ovlasti, lažiranje AD-SIGNEDPATH ili AD-KDC-ISSUED potpisa te za pokretanje napada uskraćivanja usluge. S obzirom na to da su objavljena rješenja koja uklanjaju spomenute ranjivosti, svim se korisnicima savjetuje njihova primjena.
