Name of the Vulnerable Software and Affected Versions:
BusyBox versions prior to 1.30.0
Description:
An issue in the udhcp components of BusyBox allows a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is due to an out of bounds read related to verification in
udhcp get option() in networking/udhcp/common.c that 4-byte options are indeed 4 bytes.Recommendations:
For versions prior to 1.30.0, update to version 1.30.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the DHCP server, client, and relay to minimize the risk of exploitation.
