More information:

A vulnerability has been found in the ASN.1 parser of strongSwan, an IKE/IPsec suite used to establish IPsec protected links.

By sending a crafted ID_DER_ASN1_DN ID payload to a vulnerable pluto or charon daemon, a malicious remote user can provoke a null pointer dereference in the daemon parsing the identity, leading to a crash and a denial of service.
