samples/geotag.cpp in the example code of Exiv2 0.26 misuses the realpath function on POSIX platforms (other than Apple platforms) where glibc is not used, possibly leading to a buffer overflow.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
