Changelog

Sourced from org.apache.httpcomponents.core5:httpcore5's changelog.

Release 5.3.5

This maintenance release fixes several corner cases in the H2 protocol handler that could have been potentially exploited to make H2 endpoints allocate extra resources and lead to Denial-of-Service conditions. This release also improves handling of H2 stream abnormal termination.

Change Log

  • Improved H2 connection termination in case of the opposite endpoint failing to send GOAWAY frame. Contributed by Oleg Kalnichevski

  • Bug fix: Corrected abnormal termination of H2 streams Contributed by Oleg Kalnichevski

  • Use RequestNotExecutedException instead of ConnectionClosedException when failing enqueued requests that never got executed. Contributed by Oleg Kalnichevski

  • H2 protocol handler to enforce a max limit on number of CONTINUATION frames. Contributed by Oleg Kalnichevski

  • Bug fix: Fixed a potential 'End Stream Headers' vulnerability and adds test coverage for various HTTP/2 stream reset exploits. Contributed by Oleg Kalnichevski

  • Improved ContentType Javadoc. Contributed Winfried Gerlach <Winfried.Gerlach at draeger.com>

  • HTTPCORE-782: Non-blocking TLS session can end up in an endless loop in case of a protocol negotiation. Contributed by Oleg Kalnichevski

  • Slightly better and efficient #toHexString method. Contributed by Oleg Kalnichevski
