Upgrade thrift to version 0.24.0 or higher.
Overview
thrift is a Python bindings package for Apache Thrift.
Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data (Data Amplification) through the ZLIB read path in thrift.transport.THeaderTransport.THeaderTransport. An attacker can force excessive memory and CPU use by sending a header-framed request with a small compressed payload that expands into a very large decompressed body. When THeaderTransport.readFrame() processes the THeaderTransformID.ZLIB transform, it unconditionally decompresses the payload with zlib.decompress(), so a compression bomb can amplify input into an oversized message and exhaust the Python process or service handling the request.
