Version 4.3.1¶

• The nm plugin now passes DNS/NBNS server information to NetworkManager,
  allowing a gateway administrator to set DNS/NBNS configuration on clients
  dynamically.

• The nm plugin also accepts CA certificates for gateway authentication. If
  a CA certificate is configured, strongSwan uses the entered gateway address
  as its idenitity, requiring the gateways certificate to contain the same as
  subjectAltName. This allows a gateway administrator to deploy the same
  certificates to Windows 7 and NetworkManager clients.

• The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA.
  The command ipsec down <conn>{n} deletes CHILD SA instance n of connection
  <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances.
  The command ipsec down <conn>[n] deletes IKE SA instance n of connection
  <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all
  IKE SA instances of connection <conn>.

• Fixed a regression introduced in 4.3.0 where EAP authentication calculated
  the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation
  has been updated to be compatible with the Windows 7 Release Candidate.

• Refactored installation of triggering policies. Routed policies are handled
  outside of IKE_SAs to keep them installed in any case. A tunnel gets
  established only once, even if initiation is delayed due network outages.

• Improved the handling of multiple acquire signals triggered by the kernel.

• Fixed two DoS vulnerabilities in the charon daemon that were discovered by
  fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an
  incomplete state which caused a null pointer dereference if a subsequent
  CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either
  a missing TSi or TSr payload caused a null pointer derefence because the
  checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was
  developped by the Orange Labs vulnerability research team. The tool was
  initially written by Gabriel Campana and is now maintained by Laurent Butti.

• Added support for AES counter mode in ESP in IKEv2 using the proposal
  keywords aes128ctr, aes192ctr and aes256ctr.

• Further progress in refactoring pluto: Use of the curl and ldap plugins
  for fetching crls and OCSP. Use of the random plugin to get keying material
  from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative
  to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and
  serpent encryption plugins are now optional and are not enabled by default.
