CVE-2019-11939: Facebook Thrift

High severity, CVSS 7.5. EPSS: 1.6% chance of exploitation in the next 30 days.

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.

Affected products
