Summary

Golang Facebook Thrift servers vulnerable to denial of service

Description

Golang Facebook Thrift servers would not error upon receiving messages declaring containers of sizes larger than the payload. As a result, malicious clients could send short messages which would result in a large memory allocation, potentially leading to denial of service. This issue affects Facebook Thrift prior to v2020.03.16.00.
