NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-sk-dummy-debuginfo package and not the openssh-sk-dummy-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection.
