A heap-based buffer overflow exists in the qr_reader_match_centers function
of ZBar 0.23.90. Specially crafted QR codes may lead to information
disclosure and/or arbitrary code execution. To trigger this vulnerability,
an attacker can digitally input the malicious QR code, or prepare it to be
physically scanned by the vulnerable scanner.
