Description

Impact

The original report:

Server handling of 100-Continue requests can lead to memory leak that can be abused to cause a Denial of Service state.

After investigation, turns out that every request that has a body, but reading the body may end up in reading 0 bytes, leaks a buffer. This is particularly the case for 100-Continue, but any request where the network is slow can leak.
