OpenSSH: Permission issue A flaw has been discovered in OpenSSH which could allow a remote attacker to create zero-length files. OpenSSH 2018-01-07 2018-01-07 633428 remote 7.5_p1-r3 7.5_p1-r3

OpenSSH is a complete SSH protocol implementation that includes SFTP client and server support.

The process_open function in sftp-server.c in OpenSSH did not properly prevent write operations in readonly mode.

A remote attacker could cause the creation of zero-length files.

There is no known workaround at this time.

All OpenSSH users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/openssh-7.5_p1-r3" CVE-2017-15906 jmbailey jmbailey
