+Subject: [PATCH] Fix for CVE-2017-14864, CVE-2017-14862 and CVE-2017-14859
+
+The invalid memory dereference in
+Exiv2::getULong()/Exiv2::StringValueBase::read()/Exiv2::DataValue::read()
+is caused further up the call-stack, by
+v->read(pData, size, byteOrder) in TiffReader::readTiffEntry()
+passing an invalid pData pointer (pData points outside of the Tiff
+file). pData can be set out of bounds in the (size > 4) branch where
+baseOffset() and offset are added to pData_ without checking whether
+the result is still in the file. As offset comes from an untrusted
+source, an attacker can craft an arbitrarily large offset into the
+file.
+
+This commit adds a check into the problematic branch, whether the
+result of the addition would be out of bounds of the Tiff
+file. Furthermore the whole operation is checked for possible
+overflows.

+Subject: [PATCH] Fix for CVE-2017-14860
+
+A heap buffer overflow could occur in memcpy when icc.size_ is larger
+than data.size_ - pad, as then memcpy would read out of bounds of data.
+
+This commit adds a sanity check to iccLength (= icc.size_): if it is
+larger than data.size_ - pad (i.e. an overflow would be caused) an
+exception is thrown.
+
+This fixes #71.
