NVD Description

Note: Versions mentioned in the description apply only to the upstream busybox package and not the busybox package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
