CVE-2023-40889

A heap-based buffer overflow existed in the qr_reader_match_centers function. 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.

CVE-2023-40890

A stack overflow was present in lookup_sequence function. 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.

For Debian 10 buster, these problems have been fixed in version 0.22-1+deb10u1.

We recommend that you upgrade your zbar packages.

For the detailed security status of zbar please refer to its security tracker page at: [link moved to references]
