Photon OS 4.0: Ruby PHSA-2021-4.0-0084

high Nessus Plugin ID 152796

Synopsis

The remote PhotonOS host is missing multiple security updates.

Description

An update of the ruby package has been released.

 - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected Linux packages.
