referenced in the USN-3230-1 advisory.

    It was discovered that Pillow incorrectly handled certain compressed text chunks in PNG images. A remote
    attacker could possibly use this issue to cause Pillow to crash, resulting in a denial of service. This
    issue only affected Ubuntu 14.04 LTS. (CVE-2014-9601)

    Cris Neckar discovered that Pillow incorrectly handled certain malformed images. A remote attacker could
    use this issue to cause Pillow to crash, resulting in a denial of service, or possibly obtain sensitive
    information. (CVE-2016-9189)

    Cris Neckar discovered that Pillow incorrectly handled certain malformed images. A remote attacker could
    use this issue to cause Pillow to crash, resulting in a denial of service, or possibly execute arbitrary
    code. (CVE-2016-9190)
