Digest authentication lossy encoding
In Eclipse Jetty, the Digest authentication server-side component uses ISO-8859-1 to encode the password as bytes. This was done because the initial specification for HTTP did not specify explicitly a charset, and it was assumed to be ISO-8859-1 for historica…

Eclipse Jetty: DoS attack triggering OutOfMemory with 100-Continue requests
For requests that have a body, but reading the body may end up in reading 0 bytes, there is a buffer leak. This is particularly the case for 100-Continue, but any request where the network is slow can leak.
