EulerOS Virtualization 3.0.2.2 : ruby (EulerOS-SA-2021-2167)

high Nessus Plugin ID 151390

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 :

 - Onigmo through 6.2.0 has a NULL pointer dereference in onig_error_code_to_str because of fetch_token in regparse.c.(CVE-2019-16161)

 - Onigmo through 6.2.0 has an out-of-bounds read in parse_char_class because of missing codepoint validation in regenc.c.(CVE-2019-16162)

 - An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack.(CVE-2020-25613)

 - There is an OS command injection vulnerability in Ruby Rake < 12.3.3 in Rake::FileList when supplying a filename that begins with the pipe character `|`.(CVE-2020-8130)

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.
