Debian LTS Advisory DLA-3566-1 [email protected]
https://www.debian.org/lts/security/ Sylvain Beucler
September 13, 2023 https://wiki.debian.org/LTS
Package : ruby-rails-html-sanitizer
Version : 1.0.4-1+deb10u2
CVE ID : CVE-2022-23517 CVE-2022-23518 CVE-2022-23519 CVE-2022-23520
Debian Bug : 1027153
Multiple vulnerabilities were discovered in Rails HTML Sanitizers, an
HTML sanitization library for Ruby on Rails applications. An attacker
could launch cross-site scripting (XSS) and denial-of-service (DoS)
attacks through crafted HTML/XML documents.
CVE-2022-23517
Certain configurations use an inefficient regular expression that
is susceptible to excessive backtracking when attempting to
sanitize certain SVG attributes. This may lead to a denial of
service through CPU resource consumption.
CVE-2022-23518
Cross-site scripting via data URIs when used in combination with
Loofah >= 2.1.0.
CVE-2022-23519
XSS vulnerability with certain configurations of
Rails::Html::Sanitizer may allow an attacker to inject content if
the application developer has overridden the sanitizer's allowed
tags in either of the following ways: allow both "math" and
"style" elements, or allow both "svg" and "style" elements.
CVE-2022-23520
XSS vulnerability with certain configurations of
Rails::Html::Sanitizer due to an incomplete fix of
CVE-2022-32209. Rails::Html::Sanitizer may allow an attacker to
inject content if the application developer has overridden the
sanitizer's allowed tags to allow both "select" and "style"
elements.
For Debian 10 buster, these problems have been fixed in version
1.0.4-1+deb10u2.
We recommend that you upgrade your ruby-rails-html-sanitizer packages.
