DSA-098-1 libgtop -- formatstrengssårbarhed og bufferoverløb
- Rapporteret den:
- 9. jan 2002
- Berørte pakker:
- libgtop
- Sårbar:
- Ja
- 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.
