CVE-2017-15906  (opens in a new tab)
CWE-732  (opens in a new tab)

How to fix?

Upgrade Oracle:7 openssh to version 0:7.4p1-16.el7 or higher.
This issue was patched in ELSA-2018-0980.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Oracle. See How to fix? for Oracle:7 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.
