CVE-2019-11938: Facebook Thrift

High severity, CVSS 7.5. EPSS: 2.3% chance of exploitation in the next 30 days.

Java 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 v2019.12.09.00.
