Synopsis
=======
A vulnerability has been discovered in protobuf-java which could result
in denial of service.

Background
=========
protobuf-java contains the Java bindings for Google's Protocol Buffers.

Affected packages
================

Description
==========
Inputs containing multiple instances of non-repeated embedded messages
with repeated or unknown fields causes objects to be converted back and
forth between mutable and immutable forms, resulting in potentially long
garbage collection pauses.

Impact

collection pauses.

Workaround
