EulerOS Virtualization 3.0.6.6 : ruby (EulerOS-SA-2022-2536)
high Nessus Plugin ID 165918
Synopsis
The remote EulerOS Virtualization host is missing multiple security updates.Description
According to the versions of the ruby packages installed, the EulerOS Virtualization 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)
- CGI::Cookie.parse in Ruby through 2.6.8 mishandles security prefixes in cookie names. This also affects the CGI gem through 0.3.0 for Ruby. (CVE-2021-41819)
- There is a buffer over-read in Ruby before 2.6.10, 2.7.x before 2.7.6, 3.x before 3.0.4, and 3.1.x before 3.1.2. It occurs in String-to-Float conversion, including Kernel#Float and String#to_f. (CVE-2022-28739)
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.
