Overview
Affected versions of this package are vulnerable to Integer Underflow (Wrap or Wraparound) in the exif_mnote_data_get_value() function when a size of 0 is passed as an argument during decoding MakerNotes. An attacker can cause the in-buffer to be overwritten and potentially execute arbitrary code or access sensitive information by supplying a crafted input that triggers an integer underflow.
