[Security] Bump rdoc from 3.12 to 6.3.1

[dependabot-preview]

Bumps rdoc from 3.12 to 6.3.1. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

RDoc OS command injection vulnerability RDoc used to call Kernel#open to open a local file. If a Ruby project has a file whose name starts with | and ends with tags, the command following the pipe character is executed. A malicious Ruby project could exploit it to run an arbitrary command execution against a user who attempts to run rdoc command.

Patched versions: >= 6.3.1 Unaffected versions: none

Sourced from The Ruby Advisory Database.

RDoc 2.3.0 through 3.12 XSS Exploit Doc documentation generated by rdoc 2.3.0 through rdoc 3.12 and prereleases up to rdoc 4.0.0.preview2.1 are vulnerable to an XSS exploit. This exploit may lead to cookie disclosure to third parties.

The exploit exists in darkfish.js which is copied from the RDoc install location to the generated documentation.

RDoc is a static documentation generation tool. Patching the library itself is insufficient to correct this exploit.

This exploit was discovered by Evgeny Ermakov .

Patched versions: ~> 3.9.5; ~> 3.12.1; >= 4.0 Unaffected versions: none

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects rdoc darkfish.js in RDoc 2.3.0 through 3.12 and 4.x before 4.0.0.preview2.1, as used in Ruby, does not properly generate documents, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted URL.

Affected versions: >= 2.3.0, < 3.12.1
