Apache Thrift vulnerability analysis and mitigation
Overview
CVE-2019-11939 affects Golang Facebook Thrift servers prior to version v2020.03.16.00. The vulnerability stems from the servers' failure to properly validate container sizes against message payloads. This issue was discovered and disclosed in March 2020 (NVD, MITRE).
Technical details
The vulnerability occurs when Golang Facebook Thrift servers receive messages declaring containers with sizes larger than the actual payload. The servers would not generate an error in these cases, leading to potential memory allocation issues. The vulnerability has a CVSS 3.1 Base Score of 7.5 (High) (Ubuntu).
Impact
When exploited, malicious clients could send short messages that would trigger large memory allocations on the server, potentially leading to denial of service conditions (MITRE).
Mitigation and workarounds
The issue was fixed in Facebook Thrift version v2020.03.16.00. The patch includes validation of container size against total message size and confirms that the message is theoretically large enough to contain a list/map/set of the given size (Github).
