Application denial of service via integer overflow in BSON value-length validation in MongoDB Go Driver
CVSS Score
5.9
EPSS Score
0.0%
EPSS Percentile
0th
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.
