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
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-java/protobuf-java     < 3.20.3                    >= 3.20.3

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
======

Crafted input can trigger a denial of service via long garbage
collection pauses.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All protobuf-java users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-java/protobuf-java-3.20.3"
