Debian 5.0: DSA-1899-1 Critical: StrongSwan Denial of Service Issues

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.
