Description

  • Fixes an over-read into TLS transfer serialization ASN.1 data and caps it to the appropriate amount.
  • Sets key_update_pending to the value that was actually deserialized. This originally was thought to be addressed in 26da017 but while deserialization was done, the value was still not being set.
