Eclipse Jetty: DoS attack triggering OutOfMemory with 100-Continue requests
### 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. ### Affected Versions * Jetty 11.0.0-11.0.22 (EOL) * Jetty 10.0.0-10.0.22 (EOL) ### Patched Versions * Jetty 11.0.23 * Jetty 10.0.23 ### Patches https://github.com/jetty/jetty.project/pull/12156 ### Workarounds No workarounds.
