Descriptions

A stack-based buffer overflow vulnerability exists in the lookup_sequence 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.

It was discovered that ZBar did not properly handle certain QR codes. If a user or automated system using ZBar were tricked into opening a specially crafted file, an attacker could possibly use this to obtain sensitive information.
