Denial of Service (DoS)

protobuf is a Google’s data interchange format

Affected versions of this package are vulnerable to Denial of Service (DoS) via the MessageSet type, by allowing an attacker to send specially crafted message with multiple key-value per elements, therefore creating parsing issues against services which receive unsanitized input.

How to fix Denial of Service (DoS)?

Upgrade protobuf to version 3.18.3, 3.19.5, 3.20.2, 4.21.6 or higher.
