Rapporteret den:

Sårbar:

Referencer i sikkerhedsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 3049.
I Mitres CVE-ordbog: CVE-2001-0977.
CERTs noter om sårbarheder, bulletiner og hændelser: CA-2001-18.

Yderligere oplysninger:

CERT-bulletinen opremser et antal sårbarheder i forskellige implementeringer af LDAP, baseret på resultaterne af PROTOS LDAPv3-testsuite. Disse test fandt et problem i OpenLDAP, en fri LDAP-implementering der distribueres som en del af Debian GNU/Linux 2.2.

Problemet er at slapd ikke kunne håndtere pakker som havde BER-felter med en ugyldig længe og gik ned hvis det modtog dem. En angriber kunne benytte dette til at sætte et fjern-overbelastningsangreb ("denial of service") i gang.

Dette problem er rettet i version 1.2.12-1, og vi anbefaler at du omgående opgraderer din slapd-pakke.

Rettet i:

Debian GNU/Linux 2.2 (potato)
