Vulnerability CVE-2019-5747

Vulnerability Name:

CVE-2019-5747 (CCN-155474)

Assigned:

2019-01-08

Published:

2019-01-08

Updated:

2022-10-29

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.
