Alpine: multiple openssh packages: security update to 6.9-r0 (deprecated)

high Tenable Cloud Security Plugin ID 401134

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict
the processing of keyboard-interactive devices within a single connection, which makes it easier for
remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long
and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that
provides a different password for each pam element on this list. (CVE-2015-5600)
