There is no fixed version for Ubuntu:12.04 openssh.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Ubuntu. See How to fix? for Ubuntu:12.04 relevant fixed versions and status.

The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files.
