Alpine: multiple putty packages: security update to 0.76-r0

high Tenable Cloud Security Plugin ID 406597

Description

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

 - PuTTY through 0.75 proceeds with establishing an SSH session even if it has never sent a substantive
 authentication response. This makes it easier for an attacker-controlled SSH server to present a later
 spoofed authentication prompt (that the attacker can use to capture credential data, and use that data for
 purposes that are undesired by the client user). (CVE-2021-36367)
