    An integer overflow vulnerability might lead into a denial of service
    or disclosure of portion of application memory if an attacker has
    control on the input file.

CVE-2015-4844

    Buffer overflow vulnerabilities might allow an attacker with control
    on the font file to perform a denial of service attacker or,
    possibly, execute arbitrary code.

    Integer signedness issues were introduced as part of the
    CVE-2015-4844 fix.
