Teach "tiffinfo -D" to not try to print image data inside an EXIF subdirectory,
|
|
|
6456d8 |
because there isn't any. Back-patched from an upstream 4.0.2 fix.

This is not a security issue in itself (it crashes, but with a simple NULL
|
|
|
6456d8 |
pointer dereference). However, our test case for CVE-2012-5581 tickles this
|
|
|
6456d8 |
bug, so it seems easier to fix this than make a new test case.
