Rapporterat den:

Sårbara:

Referenser i säkerhetsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 3049.
I Mitres CVE-förteckning: CVE-2001-0977.
CERTs information om sårbarheter, bulletiner och incidenter: CA-2001-18.

Ytterligare information:

CERTs bulletin visar på ett antal sårbarheter i diverse LDAP-implementationer, baserade på resultaten för PROTOS LDAPv3-testsvit. Dessa tester hittade ett problem i OpenLDAP, en fri LDAP-implementation som medföljer Debian GNU/Linux 2.2.

Problemet är att slapd inte hanterade paket vilka hade BER-fält med ogiltig längd, och kraschade när sådana togs emot. En angripare kunde använda detta för att utföra en överbelastningsattack utifrån.

Detta problem har rättats i version 1.2.12-1, och vi rekommenderar att du uppgraderar ditt slapd-paket omedelbart.

Debian GNU/Linux 2.2 (potato)
