Summary

MongoDB Go Driver versions from 1.0.0 before 1.2.0 and from 2.0.0 before 2.9.0 are affected. An integer overflow in BSON value-length handling (CWE-190) can cause a runtime panic when an application validates or accesses a malformed BSON document. An unauthenticated attacker who can supply BSON bytes to an affected application can terminate an unprotected application process, causing a denial of service.

Description from the CNA

An integer overflow in BSON value-length handling in the MongoDB Go Driver can cause a runtime panic when an application validates or accesses a malformed BSON document. An unauthenticated actor who can supply BSON bytes to an affected application may terminate an unprotected application process, causing a denial of service. The driver's server-monitoring path contains panic recovery and is limited to server-selection failure.
