Yderligere oplysninger:

Flere fjernudnytbare sårbarheder er opdaget i racoon, ipsec-tools' Internet Key Exchange-dæmon. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

CVE-2009-1574
Neil Kettle opdagede en NULL-pointerdereference ved fabrikerede fragmenterede pakker uden indhold. Det medførte at dæmonen gik ned, hvilket kunne anvendes i lammelsesangreb (denial of service).
CVE-2009-1632
Forskellige hukommelseslækager i autentificeringshåndteringen af X.509-certifikater og implementeringen af NAT-Traversal-keepalive, kunne medføre opbrugt hukommelse og dermed lammelsesangreb.

I den gamle stabile distribution (etch), er dette problem rettet i version 0.6.6-3.1etch3.

I den stabile distribution (lenny), er dette problem rettet i version 0.7.1-1.3+lenny2.

I distributionen testing (squeeze), vil dette problem snart blive rettet.

I den ustabile distribution (sid), er dette problem rettet i version 1:0.7.1-1.5.

Vi anbefaler at du opgraderer dine ipsec-tools-pakker.
