Name of the Vulnerable Software and Affected Versions
ZBar version 0.23.90
Description
A heap-based buffer overflow exists in the

For ZBar version 0.23.90, consider disabling the
qr reader match centers function until a patch is available to prevent potential exploitation. Restrict the input of QR codes to trusted sources to minimize the risk of information disclosure and/or arbitrary code execution. At the moment, there is no information about a newer version that contains a fix for this issue.Exploit
