EulerOS 2.0 SP8 : ruby (EulerOS-SA-2021-2643)

medium Nessus Plugin ID 154785

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. 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)

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.
