-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.
