tornado AsyncHTTPClient accumulates decompressed chunks without size limit (gzip bomb)

Tornado's gzip decompression routines work in limited-size chunks, but have no overall limit for the total size of decompressed chunks that they will accumulate There has always been a limit for the total compressed size. This allows a malicious server to consume effectively unlimited amounts of...

Improper Handling of Highly Compressed Data (Data Amplification)

Overview Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification during cleanup. An attacker can exhaust system memory by sending a specially crafted compressed payload that is decompressed into memory in a single chunk. Remediation Upgra...

org.eclipse.jetty/jetty-server: Eclipse Jetty: Denial of Service due to unreleased JDK Inflater from compressed HTTP requests

A flaw was found in org.eclipse.jetty. A remote attacker can exploit this vulnerability by sending a compressed HTTP request with Content-Encoding: gzip when the server's response is not compressed. This prevents the release of the JDK Inflater, leading to a resource leak. This resource exhaustio...
