Several security issues were fixed in yard.

Summary

Several security issues were fixed in yard.

Software Description:

- yard: Ruby documentation tool

Details:

It was discovered that YARD before 0.9.11 does not block relative paths

with an initial ../ sequence, which allows attackers to conduct

directory traversal attacks and read arbitrary files. This issue only

affected Ubuntu 16.04 LTS. (CVE-2017-17042)

It was discovered that yard before 0.9.20 is affected by a path

traversal vulnerability, allowing HTTP requests to access arbitrary

files under certain conditions. This issue only affected Ubuntu 18.04

LTS. (CVE-2019-1020001)

Aviv Keller discovered that the "frames.html" file within the Yard

Doc's generated documentation is vulnerable to Cross-Site Scripting

(XSS) attacks due to inadequate sanitization of user input within the

JavaScript segment of the "frames.erb" template file. (CVE-2024-27285)
