Overview
Affected versions of this package are vulnerable to Double Free via the fz_fill_pixmap_from_display_list function when an exception occurs during display list rendering. An attacker can cause heap corruption and crash the process by providing crafted input that triggers a rendering-time error during barcode decoding. This is only exploitable if barcode decoding is enabled and used.
