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 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEwv5L0nHBObhsUz5GHpU+J9QxHlgFAmVTTOsACgkQHpU+J9Qx Hli3Yg/+Pkb51r5xxPwS2g/pGpC1Md3oPsbSMFpR9claKncjS6z4EpixfDGPFDqZ GIgIJjSieGV9Wbc6fBYXT9gsSUPCugCfoYqvc1EFtXEO3C+l+05/5qcfQpGMtYzT xX7gwotN2A0AvhZ0IjTowf3XF4/Y+bMZK51YQ81S8l6DsiEQngpgt2l9/c3OvPlI RGIBufjEyBWHyayQ17jVsAAm3Edo++XFK97eYf0BPcdX5RpiOATSw88nBytqQWQG g2/5c9bGCvmdUefZ5agMEcLolKcfdIZTuQnX1BMj+RVTLjd4nSi3S/roE3NAl2WC Dpgpyqved7Vx3xZp6IzJaay9jNNY9MvDE0hvtvth3YbvwFiJFD74uDTvvCBUcbJf 81mMuyNBxLofL7WhgO/9CDqIdNSSaMKmEnkbrPDDO9XI2DchI3JU0zmHhH0VMxz+ xGSZhJ5LOTDMdwH7ln10MD2mN1QyqfVwQeXfv6kP0slD+PjUYazrr+RHEAOT/iXe xJtDD/GDENfgIE633YSHLJ4cSRI0s/OFPPBH+xHjRArbE1oyo2aYEnDOTn2T2UIe V90Ur4OuWvGH/5/XfX/G6gYjVaXv6IAflfRKW9lI5f09tt5E7azYdv+/oVhHTPdn XSFK13stKQFHroolcKjQxwYOqyUpQ8R2vJkVmtyRqhjN1lLXfIg= =YO4t -----END PGP SIGNATURE-----
