CVE-2024-42040 Open this link in a new tabHow to fix?
There is no fixed version for u-boot.
Overview
Affected versions of this package are vulnerable to Buffer Overflow via the net/bootp.c process. An attacker on the local network can leak memory ranging from four to 32 bytes stored behind the packet to the network by sending crafted DHCP responses.
##Mitigation
It is recommended that an adequate length be provided to bootp_process_vendor to prevent the while loop from stepping outside the packet frame and check in bootp_process_vendor_field if the copied data is still within the packet structure's range.
