Technical details

An out-of-bounds write (CWE-787) exists in Das U-Boot through version 2019.07. The vulnerability is caused by an unbounded memcpy operation within the 'nfs_read_reply' function when calling 'store_block' during NFSv3 operations. Specifically, a failed or missing length check on data received from a network-reachable NFS server allows for a buffer overflow. An attacker controlled NFS server could provide a malicious response to trigger this overflow, potentially leading to remote code execution (RCE) before the operating system has even loaded. Siemens has also identified this as affecting various Ruggedcom Rox II industrial devices that utilize the vulnerable U-Boot code.
