Overview

Affected versions of this package are vulnerable to Integer Overflow or Wraparound through the SCSI READ(10) or WRITE(10) commands initiated via USB. An attacker can access or modify memory contents by sending specially crafted SCSI commands with specific LBA and block count parameters. This is only exploitable if the attacker has physical or logical access to the USB interface.
