Overview

Affected versions of this package are vulnerable to Buffer Overflow in fx_fault_tolerant_apply_logs.c. When a valid log file with correct ID and checksum is detected by the _fx_fault_tolerant_enable function an attempt to recover the previous failed write operation calls _fx_fault_tolerant_apply_logs. Processing a log including entries of type FX_FAULT_TOLERANT_DIR_LOG_TYPE can allow memory manipulation and unexpected behavior.
