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

How to fix?

Upgrade Debian:11 openssh to version 1:7.6p1-1 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 Debian. See How to fix? for Debian:11 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.
