    Synopsis
    ========

    A vulnerability in libmaxminddb could lead to a Denial of Service
    condition.

    Background

    files, including the GeoIP2 databases from MaxMind.

    Description
    ===========

    libmaxminddb used uninitialised memory when reading from a corrupt
    database file.

    Impact

    Resolution
