Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for strongswan.

CVE-2009-2661[0]:
| The asn1_length function in strongSwan 2.8 before 2.8.11, 4.2 before
| 4.2.17, and 4.3 before 4.3.3 does not properly handle X.509
| certificates with crafted Relative Distinguished Names (RDNs), which
| allows remote attackers to cause a denial of service (pluto IKE daemon
| crash) via malformed ASN.1 data.  NOTE: this is due to an incomplete
| fix for CVE-2009-2185.

If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
