Debian LTS Advisory DLA-3652-1 [email protected]
https://www.debian.org/lts/security/ Chris Lamb
November 14, 2023 https://wiki.debian.org/LTS
Package : ruby-sanitize
Version : 4.6.6-2.1~deb10u2
CVE ID : CVE-2023-36823
Debian Bug : 1041430
It was discovered that there was a potential cross-site scripting
(XSS) in ruby-sanitize, a whitelist-based HTML sanitizer.
Using carefully crafted input, an attacker may have be able to sneak
arbitrary HTML and CSS through Sanitize when configured to use the
built-in "relaxed" config or when using a custom config that allowed
"style" elements and one or more CSS "at"-rules. This could have
resulted in cross-site scripting (XSS) or other undesired behavior
if the malicious HTML and CSS were then rendered in a browser.
For Debian 10 buster, this problem has been fixed in version
4.6.6-2.1~deb10u2.
We recommend that you upgrade your ruby-sanitize packages.
For the detailed security status of ruby-sanitize please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/ruby-sanitize
