Hi,
the following vulnerability was published for exiv2.
CVE-2017-18005[0]:
| Exiv2 0.26 has a Null Pointer Dereference in the
| Exiv2::DataValue::toLong function in value.cpp, related to crafted
| metadata in a TIFF file.
The underlying issue according to [2] is that the code is trying to
pring a value in the if statement:
if (Params::instance().printItems_ & Params::prValue)
when this might not be possible. Fix is done via [2].
If you fix the vulnerability please also make sure to include the

Please adjust the affected versions in the BTS as needed, please
double check my assessment for it back to 0.24-1 is done right.
The poc does not trigger, if I'm not completely wrong the affected
code is there.
Regards,
Salvatore
