Technical details

A stack-based buffer overflow exists in the NFS (Network File System) implementation of Das U-Boot. The vulnerability is located in the 'nfs_readlink_reply' function, where an unbounded 'memcpy' operation occurs using an unvalidated length value after calculating a new path length. A remote attacker on the network could provide a specially crafted NFS reply to trigger this overflow. Successful exploitation could lead to arbitrary code execution or a denial-of-service condition during the boot phase. The issue is confirmed in versions through 2019.07 and has been addressed in downstream products like Siemens Ruggedcom Rox in version 2.17.1.
