Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2023-06-08 04:14:56 UTC 
CVE-2023-31606:

A Regular Expression Denial of Service (ReDoS) issue was discovered in the sanitize_html function of redcloth gem v4.0.0. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

"There is a security vulnerability in this gem. I tried to communicate with the maintainers in an email, but still haven't got a response, I'm raising the issue here."
Comment 1 Hans de Graaff gentoo-dev Security 2023-07-09 06:01:29 UTC 
A patch is now available upstream since a few days. Let's wait a few days to see if a new gem version is released, otherwise we can apply it ourselves.
Comment 2 Hans de Graaff gentoo-dev Security 2023-07-21 17:52:07 UTC 
Looks like the maintainer is no longer active and I don't expect a new release. I've pulled in the upstream pull request instead.
