It easily crashes with various issues (tested version 9.28.0). This was
very shallow testing (afl fuzzing with random inputs, not starting with
valid images), I assume there's much more. I reported those a long time
ago to its author, he didn't seem interested in fixing such issues.

Some applications use dcraw automatically to parse images (gthumb,
kphotoalbum, kde thumbnailers, gwenview).

An important side note: because dcraw intentionally doesn't provide a
library, only an executable, code from it is bundled in at least some
applications that use it; thus updating the dcraw package in a distro
will not by itself be the end of this problem for the distro.  One such
application : RawTherapee
