Several remote vulnerabilities have been discovered in strongswan, an
implementation of the IPSEC and IKE protocols.  The Common
Vulnerabilities and Exposures project identifies the following
problems:

CVE-2009-1957
CVE-2009-1958

The charon daemon can crash when processing certain crafted IKEv2
packets.  (The old stable distribution (etch) was not affected by
these two problems because it lacks IKEv2 support.)

CVE-2009-2185
CVE-2009-2661

The pluto daemon could crash when processing a crafted X.509
certificate.

For the old stable distribution (etch), these problems have been fixed
in version 2.8.0+dfsg-1+etch2.

For the stable distribution (lenny), these problems have been fixed in
version 4.2.4-5+lenny3.

For the unstable distribution (sid), these problems have been fixed in
version 4.3.2-1.1.

We recommend that you upgrade your strongswan packages.
