NVD Description

Note: Versions mentioned in the description apply only to the upstream busybox package and not the busybox package as distributed by Alpine. See How to fix? for Alpine:3.13 relevant fixed versions and status.

An issue was discovered in BusyBox through 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP client, server, and/or relay) might allow a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to assurance of a 4-byte length when decoding DHCP_SUBNET. NOTE: this issue exists because of an incomplete fix for CVE-2018-20679.
