Name of the Vulnerable Software and Affected Versions Protobuf-c version 1.4.0

Description The issue is related to an invalid arithmetic shift via the parse tag and wiretype function in protobuf-c/protobuf-c.c, which can cause a Denial of Service (DoS) via unspecified vectors. This is also associated with errors in resource release. The exploitation of this issue allows a remote attacker to cause a service disruption.

Recommendations For Protobuf-c version 1.4.0, consider disabling the parse tag and wiretype function as a temporary workaround until a patch is available. Restrict access to the protobuf-c/protobuf-c.c component to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
