EulerOS 2.0 SP3 : ruby (EulerOS-SA-2021-2614)

high Nessus Plugin ID 154369

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ruby packages.
