Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the parse_options process. An attacker can cause the parser to read beyond the intended buffer boundary by sending a crafted DHCP request with manipulated option lengths, potentially leading to access of adjacent heap memory. This is only exploitable if the device is configured to operate as a DHCP server, such as in SoftAP mode or when acting as a DHCP server on a local network.
