CERTs noter om sårbarheder, bulletiner og hændelser: VU#795632, VU#866472, VU#550464, VU#350792.

Yderligere oplysninger:

MIT Kerberos Development-holdet har opdaget en række sårbarheder i MIT Kerberos Version 5-programmellet. Projektet Common Vulnerabilities and Exposures har fundet frem til følgende sårbarheder:

CAN-2004-0642 [VU#795632]
En dobbelt frigivelsesfejl kan gøre det muligt for uautoriserede fjernangribere at udføre vilkårlig kode på KDC eller klienter.
CAN-2004-0643 [VU#866472]
Flere dobbelt frigivelsesfejl kan gøre det muligt for autentificerede angribere at udføre vilkårlig kode på Kerberos-applicationsservere.
CAN-2004-0644 [VU#550464]
Et lammelsesangrebssårbarhed der kan udnyttes af en fjernangriber er fundet i KDC og biblioteker.
CAN-2004-0772 [VU#350792]
Flere dobbelt frigivelsesfejl kan gøre det muligt for fjernangribere at udføre vilkårlig kode på serveren. Dette påvirker ikke versionen i "woody".

I den stabile distribution (woody) er disse problemer rettet i version 1.2.4-5woody6.

I den ustabile distribution (sid) er disse problemer rettet i version 1.3.4-3.

Vi anbefaler at du opgraderer dine krb5-pakker.
