Upgrade thrift to version 0.25.0 or higher.
Overview
thrift is a Python bindings package for Apache Thrift.
Affected versions of this package are vulnerable to Data Amplification in TZlibTransport, whose decompressed size limit stops being enforced once the limit has been exactly consumed, so decompression past that point proceeds unbounded. An attacker can exhaust the process memory by sending a compressed payload that inflates to exactly the configured limit and then continues. This requires the application to use the Python bindings with TZlibTransport, and the limit is reached and passed within a single transport, so no unusual configuration is needed.
