How to fix?

Upgrade Alpine:3.12 openssh to version 7.5_p1-r8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Alpine. See How to fix? for Alpine:3.12 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.
