Ytterligare information:

Två utifrån nåbara sårbarheter har upptäckts i OpenLDAP. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

  • CVE-2010-0211

    Funktionen slap_modrdn2mods i modrdn.c i OpenLDAP 2.4.22 kontrollerar inte returvärdet efter ett anrop till funktionen smr_normalize, vilket tillåter angripare utifrån att orsaka en överbelastning (segmenteringsfel) och möjligen exekvera godtycklig kod med hjälp av ett modrdn-anrop med en RDN-sträng som innehåller ogiltiga UTF-8-sekvenser.

  • CVE-2010-0212

    OpenLDAP 2.4.22 tillåter angripare utifrån att orsaka en överbelastning (krasch) med hjälp av ett modrdn-antop med en RDN-destinationssträng av längd noll.

För den stabila utgåvan (Lenny) har detta problem rättats i version 2.4.11-1+lenny2. (Den saknade uppdateringen för mips-arkitekturen kommer tillhandahållas inom kort.)

För den instabila utgåvan (Sid) har detta problem rättats i version 2.4.23-1.

Vi rekommenderar att ni uppgraderar era openldap-paket.
