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 Allocation of Resources Without Limits or Throttling in the TJSONProtocol, whose string length limit is present but disabled by default, so a declared string length is honored without bound unless the application sets one. An attacker can exhaust the process memory by sending a message whose JSON string field declares a length far larger than what is transmitted. This requires the application to use the Python bindings with TJSONProtocol and to have left the limit at its default, and no non default configuration is needed on the attacker's side.
