Alpine: ruby: security update to 2.6.8-r0

high Tenable Cloud Security Plugin ID 406988

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- In RDoc 3.11 through 6.x before 6.3.1, as distributed with Ruby through 3.0.1, it is possible to execute
arbitrary code via | and tags in a filename. (CVE-2021-31799)

- An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. A malicious FTP
server can use the PASV response to trick Net::FTP into connecting back to a given IP address and port.
This potentially makes curl extract information about services that are otherwise private and not
disclosed (e.g., the attacker can conduct port scans and service banner extractions). (CVE-2021-31810)

- An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does
not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-
middle attackers to bypass the TLS protections by leveraging a network position between the client and the
registry to block the StartTLS command, aka a "StartTLS stripping attack." (CVE-2021-32066)
