dhcp3

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2003-0026.
CERTs noter om sårbarheder, bulletiner og hændelser: VU#284857, CA-2003-01.

Yderligere oplysninger:

Internet Software Consortium har opdaget flere sårbarheder ved en gennemgang af ISC DHCP Daemon. Sårbarhederne befinder sig i fejlhåndteringsrutinerne i minires-biblioteket og kan udnyttes som et stakoverløb. Dette kunne give en fjernangriber mulighed for at udføre vilkårlig kode under den bruger-id, som dhcpd kører under, normalt root. Andre DHCP-servere end dhcp3 lader ikke til at være påvirket.

I den stabile distribution (woody) er dette problem rettet i version 3.0+3.0.1rc9-2.1.

Den gamle stabile distribution (potato) indeholder ikke dhcp3-pakker.

I den ustabile distribution (sid) er dette problem rettet i version 3.0+3.0.1rc11-1.

Vi anbefaler at du opgraderer din dhcp3-server-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
