Yderligere oplysninger:

To sårbarheder er opdaget i openswan, en IPSec-implementering til linux. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

CVE-2008-4190
Dmitry E. Oboukhov opdagede at livetest-værktøjet anvendte midlertidige filer på usikker vis, hvilket kunne føre til lammelsesangreb (denial of service).
CVE-2009-0790
Gerd v. Egidy opdagede at Pluto IKE-dæmonen i strongswan, var sårbar over for lammelsesangreb gennem en ondsindet pakke.

I den gamle stabile distribution (etch), er dette problem rettet i version 2.4.6+dfsg.2-1.1+etch1.

I den stabile distribution (lenny), er dette problem rettet i version 2.4.12+dfsg-1.3+lenny1.

I distributionen testing (squeeze) og i den ustabile distribution (sid), vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer dine openswan-pakker.
