The vulnerability is caused due to a boundary error within the
"readRadianceHeader()" function in src/Fileformat/rgbeio.cpp, which
can be exploited to cause a stack-based buffer overflow by e.g.
tricking a user into opening a specially crafted Radiance RGBE

also be affected.

Do not open untrusted Radiance RGBE (*.hdr) files.
