CVE-2019-11939: Allocation of Resources Without Limits or Throttling

May 24, 2022 (updated September 29, 2023)

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.
