- ------------------------------------------------------------------------- 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:
