Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2001-0927, CVE-2001-0928.

Yderligere oplysninger:

To forskellige problemer er blevet fundet i libgtop-daemon:

Laboratoriet intexxia har fundet et formatstrengsproblem i logningskoden i libgtop_daemon. Der var to logningsfunktioner som blev kaldt når en klient skulle autoriseres, hvilket kunne udnyttes af en fjernbruger.
Flavio Veloso fandt et bufferoverløb i funktionen som autoriserer klienter

Da libgtop_daemon kører som brugeren nobody kunne begge fejl benyttes til at få adgang som brugeren nobody, til et system som kører libgtop_daemon.

Begge problemer er blevet rettet i version 1.0.6-1.1 og vi anbefaler at du omgående opgraderer din libgtop-daemon-pakke.
