CVE-2019-5747 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream busybox package and not the busybox package as distributed by Debian.
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.
