Debian: DSA-1759-1 Critical: StrongSwan DoS via Malicious Packet

Gerd v. Egidy discovered that the Pluto IKE daemon in strongswan, an
IPSec implementation for linux, is prone to a denial of service attack
via a malicious packet.


For the stable distribution (lenny), this problem has been fixed in
version 4.2.4-5+lenny1.

For the oldstable distribution (etch), this problem has been fixed in
version 2.8.0+dfsg-1+etch1.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem will be fixed soon.

We recommend that you upgrade your strongswan packages.
