CVE-2019-5747 (GCVE-0-2019-5747)

Vulnerability from cvelistv5 – Published: 2019-01-09 16:00 – Updated: 2025-06-09 15:28
VLAI
Summary
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.
