  - An array indexing error exists in the Unpack::ShortLZ()
    function within file unpack15.cpp due to improper
    validation of input when decompressing RAR files. An
    unauthenticated, remote attacker can exploit this, via
    a specially crafted file, to corrupt memory, resulting
    in a denial of service condition or the execution of
    arbitrary code. (CVE-2016-2207)

  - A stack-based buffer overflow condition exists when
    handling PowerPoint files due to improper validation of
    user-supplied input while handling misaligned stream
    caches. An unauthenticated, remote attacker can exploit
    this, via a specially crafted PPT file, to cause a
    denial of service condition or the execution of
    arbitrary code. (CVE-2016-2209)

  - A stack-based buffer overflow condition exists in the
    CSymLHA::get_header() function within file Dec2LHA.dll
    due to improper validation of user-supplied input when
    decompressing LZH and LHA archive files. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted archive file, to cause a denial of
    service condition or the execution of arbitrary code.
    (CVE-2016-2210)

  - Multiple unspecified flaws exist in libmspack library
    due to improper validation of user-supplied input. An
    unauthenticated, remote attacker can exploit these, via
    a specially crafted CAB file, to corrupt memory,
    resulting in a denial of service condition or the
    execution of arbitrary code. (CVE-2016-2211)

  - A heap buffer overflow condition exists in the
    CMIMEParser::UpdateHeader() function due to improper
    validation of user-supplied input when parsing MIME
    messages. An unauthenticated, remote attacker can
    exploit this, via a specially crafted MIME message, to
    cause a denial of service condition or the execution of
    arbitrary code. (CVE-2016-3644)

  - An integer overflow condition exists in the
    Attachment::setDataFromAttachment() function within file
    Dec2TNEF.dll due to improper validation of user-supplied
    input when decoding TNEF files. An unauthenticated,
    remote attacker can exploit this, via a specially
    crafted TNEF file, to cause a denial of service
    condition or the execution of arbitrary code.
    (CVE-2016-3645)

  - An array indexing error exists in the
    ALPkOldFormatDecompressor::UnShrink() function within
    the scan engine decomposer due to improper validation of
    input when decoding ZIP files. An unauthenticated,
    remote attacker can exploit this, via a specially

vulnerabilities :

  - An array indexing error exists in the Unpack::ShortLZ()
    function within file unpack15.cpp due to improper
    validation of input when decompressing RAR files. An
    unauthenticated, remote attacker can exploit this, via
    a specially crafted file, to corrupt memory, resulting
    in a denial of service condition or the execution of
    arbitrary code. (CVE-2016-2207)

  - A stack-based buffer overflow condition exists when
    handling PowerPoint files due to improper validation of
    user-supplied input while handling misaligned stream
    caches. An unauthenticated, remote attacker can exploit
    this, via a specially crafted PPT file, to cause a
    denial of service condition or the execution of
    arbitrary code. (CVE-2016-2209)

  - A stack-based buffer overflow condition exists in the
    CSymLHA::get_header() function within file Dec2LHA.dll
    due to improper validation of user-supplied input when
    decompressing LZH and LHA archive files. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted archive file, to cause a denial of
    service condition or the execution of arbitrary code.
    (CVE-2016-2210)

  - Multiple unspecified flaws exist in libmspack library
    due to improper validation of user-supplied input. An
    unauthenticated, remote attacker can exploit these, via
    a specially crafted CAB file, to corrupt memory,
    resulting in a denial of service condition or the
    execution of arbitrary code. (CVE-2016-2211)

  - A heap buffer overflow condition exists in the
    CMIMEParser::UpdateHeader() function due to improper
    validation of user-supplied input when parsing MIME
    messages. An unauthenticated, remote attacker can
    exploit this, via a specially crafted MIME message, to
    cause a denial of service condition or the execution of
    arbitrary code. (CVE-2016-3644)

  - An integer overflow condition exists in the
    Attachment::setDataFromAttachment() function within file
    Dec2TNEF.dll due to improper validation of user-supplied
    input when decoding TNEF files. An unauthenticated,
    remote attacker can exploit this, via a specially
    crafted TNEF file, to cause a denial of service
    condition or the execution of arbitrary code.
    (CVE-2016-3645)

  - An array indexing error exists in the
    ALPkOldFormatDecompressor::UnShrink() function within
    the scan engine decomposer due to improper validation of
    input when decoding ZIP files. An unauthenticated,
    remote attacker can exploit this, via a specially
    crafted ZIP file, to corrupt memory, resulting in a
    denial of service condition or the execution of
    arbitrary code. (CVE-2016-3646)");
