Hi,
The following vulnerability was published for busybox.
CVE-2018-20679[0]:
| An issue was discovered in BusyBox before 1.30.0. An out of bounds read
| in udhcp components (consumed by the DHCP server, client, and relay)
| allows a remote attacker 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.
