    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"
