Original description
The description as published by the source.
Dislocker through 0.7.3 contains a heap out-of-bounds read vulnerability in get_dataset() and get_next_datum() that never validate dataset and datum sizes against the metadata allocation. Attackers can craft a BitLocker volume image with inflated dataset or datum sizes that, when opened or mounted, crashes dislocker or discloses adjacent heap memory.
