Пакет libstrongswan: Информация

- 4.2.17 built for M50:
  + the RDN parser vulnerability discovered by Orange Labs research team
    was not completely fixed in version 4.2.16. Some more modifications
    had to be applied to the asn1_length() function.
- thanks crux@ for prompt notification

- 4.2.16 fixes DoS vulnerability in the ASN.1 parser;
  thanks crux@ for notification (closes: #20527)

- 4.2.15 fixes two DoS issues with charon
  + 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
  + 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
  + patch2 unneeded (included upstream)
- thanks crux@ for heads-up (closes: #20206)
