Name of the Vulnerable Software and Affected Versions Protobuf versions prior to 6.31.1

Description The issue affects projects that use the Protobuf Pure-Python backend to parse untrusted Protocol Buffers data. This data can contain an arbitrary number of recursive groups, recursive messages, or a series of SGROUP tags, which can cause the application to exceed the Python recursion limit. As a result, this can lead to a Denial of Service by crashing the application with a RecursionError.

Recommendations For versions prior to 6.31.1, upgrade to version 6.31.1 or beyond commit 17838beda2943d08b8a9d4df5b68f5f04f26d901 to resolve the issue.
