In the DataBuf class in include/exiv2/types.hpp in Exiv2 0.26, an issue
exists in the constructor with an initial buffer size. A large size value
may lead to a SIGABRT during an attempt at memory allocation. NOTE: some
third parties have been unable to reproduce the SIGABRT when using the
4-DataBuf-abort-1 PoC file.
