Name of the Vulnerable Software and Affected Versions Facebook Thrift versions prior to 2019.02.18.00

Description The issue allows malicious clients to send short messages that take a long time for the server to parse, potentially leading to denial of service. This occurs because Python Facebook Thrift servers do not error upon receiving messages with containers of fields of unknown type.

Recommendations For versions prior to 2019.02.18.00, update to version 2019.02.18.00 or later to resolve the issue. As a temporary workaround, consider implementing measures to limit the parsing time of incoming messages to prevent potential denial of service attacks.
