strongswan-5.2.2
----------------
- Fixed a denial-of-service vulnerability triggered by an IKEv2 Key Exchange
payload that contains the Diffie-Hellman group 1025. This identifier was
used internally for DH groups with custom generator and prime. Because
these arguments are missing when creating DH objects based on the KE payload
an invalid pointer dereference occurred. This allowed an attacker to crash
the IKE daemon with a single IKE_SA_INIT message containing such a KE
payload. The vulnerability has been registered as CVE-2014-9221.
- The left/rightid options in ipsec.conf, or any other identity in strongSwan,
now accept prefixes to enforce an explicit type, such as email: or fqdn:.
Note that no conversion is done for the remaining string, refer to
