CERTs information om sårbarheter, bulletiner och incidenter: VU#795632, VU#866472, VU#550464, VU#350792.

Ytterligare information:

MIT Kerberos-utvecklingsgruppen upptäckte ett antal sårbarheter i MIT Kerberos version 5-programvaran. Projektet Common Vulnerabilities and Exposures identifierar följande sårbarheter:

CAN-2004-0642 [VU#795632]
En dubbel frigörning kan göra det möjligt för oautentiserade angripare utifrån att exekvera godtycklig kod på KDC eller klienter.
CAN-2004-0643 [VU#866472]
Flera fel med dubbel frigörning kan göra det möjligt för autentiserade angripare att exekvera godtycklig kod på Kerberosprogramservrar.
CAN-2004-0644 [VU#550464]
En utifrån sårbar överbelastningsattack har upptäckts i KDC och bibliotek.
CAN-2004-0772 [VU#350792]
Flera fel med dubbel frigörning kan göra det möjligt för angripare utifrån att exekvera godtycklig kod på serveren. Detta påverkar inte versionen i Woody.

För den stabila utgåvan (Woody) har dessa problem rättats i version 1.2.4-5woody6.

För den instabila utgåvan (Sid) har dessa problem rättats i version 1.3.4-3.

Vi rekommenderar att ni uppgraderar era krb5-paket.
