What happened
The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without adequate validation. Crafted documents in a GridFS collection may cause any application that reads those files via the legacy API to either crash (via a division-by-zero) or silently leak process memory contents (via an out-of-bounds read).
Affected versions
C Driver: 1.0 through before 1.30.8 (custom); 2.0 through before 2.2.4 (custom) Fixed: See vendor advisory.
