An issue exists in BusyBox prior to 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP server, client, and relay) allows a remote malicious user to leak sensitive information from the stack by sending a crafted DHCP message. This is related to verification in udhcp_get_option() in networking/udhcp/common.c that 4-byte options are indeed 4 bytes.
