DSA-075-1 netkit-telnet-ssl -- fjernangreb

Rapporteret den:

14. aug 2001

Berørte pakker:

netkit-telnet-ssl

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2001-0554.

Yderligere oplysninger:

telnet-daemon'en i pakken netkit-telnet-ssl_0.16.3-1 i Debian GNU/Linux' 'stabile' distribution (potato) er sårbar overfor et overløb i uddatahåndteringen. Fejlen blev fundet af <scut@nb.in-berlin.de> og annonceret på bugtraq den 18. juli 2001. På det tidspunkt troede man ikke at versioner af netkit-telnet efter 0.14 var sårbare.

Den 10. august 2001 postede zan-parse et bulletin baseret på det samme problem, vedrørende alle versioner af netkit-telnet under 0.17.

Flere oplysninger fås hos SecurityFocus. Da Debian anvender brugeren 'telnetd' til at køre in.telnetd er dette ikke et fjernangreb mod root-brugeren på Debian-systemer; men 'telnetd'-brugeren kan angribes.

Vi anbefaler kraftigt at du opdaterer dine netkit-telnet-ssl-pakker til versionerne angivet herunder.

Rettet i:

Debian GNU/Linux 2.2 (potato)
