1. Impact

    Multiple security vulnerabilities exist in the Tag Image File format
    library (libtiff(3)) which may affect applications making use of this
    library. Depending on the individual application, these
    vulnerabilities may allow a local or remote unprivileged user to cause
    a Denial of Service (DoS) to the application, or to execute arbitrary
    code with the privileges of the application.

    These issues are described in the following documents:

    Service (DoS), the affected application will crash, potentially
    leaving a core file depending on the system configuration.

    There are no predictable symptoms that would indicate that these
    issues have been exploited to execute arbitrary code.

4. Relief/Workaround
