1. Impact

    Several security vulnerabilities in the FreeType 2 type engine may
    allow a local unprivileged user to be able to execute arbitrary
    commands with the privileges of an application using FreeType 2 as a
    font service. These vulnerabilities may also allow a remote
    unprivileged user to either cause applications using FreeType 2 as a
    font service to crash (which is a Denial of Service (DoS)) or to
    execute arbitrary commands with the privileges of a local user.

    More information about the FreeType 2 software font engine is
    available here:
