+## javascript insertion via insufficient htmlscrubbing of comments
+
+Kevin Riggle noticed that it was not possible to configure
+`htmlscrubber_skip` to scrub comments while leaving unscubbed the text
+of eg, blog posts. Confusingly, setting it to "* and !comment(*)" did not
+scrub comments.
+
+Additionally, it was discovered that comments' html was never scrubbed during
+preview or moderation of comments with such a configuration.
+
+These problems were discovered on 12 November 2010 and fixed the same
+hour with the release of ikiwiki 3.20101112. ([[!cve CVE-2010-1673]])
+
+## javascript insertion via insufficient checking in comments
+
+Dave B noticed that attempting to comment on an illegal page name could be
+used for an XSS attack.
+
+This hole was discovered on 22 Jan 2011 and fixed the same day with
+the release of ikiwiki 3.20110122. A fix was backported to Debian squeeze,
+as version 3.20100815.5. An upgrade is recommended for sites

+## possible javascript insertion via insufficient htmlscrubbing of alternate stylesheets
+
+Giuseppe Bilotta noticed that 'meta stylesheet` directives allowed anyone
+who could upload a malicious stylesheet to a site to add it to a

+
+This hole was discovered on 28 Mar 2011 and fixed the same hour with

+## tty hijacking via ikiwiki-mass-rebuild
+
+Ludwig Nussel discovered a way for users to hijack root's tty when
+ikiwiki-mass-rebuild was run. Additionally, there was some potential
+for information disclosure via symlinks. ([[!cve CVE-2011-1408]])
+
+This hole was disconvered on 8 June 2011 and fixed the same day with
+the release of ikiwiki 3.20110608. Note that the fix is dependant on
+a version of su that has a similar hole fixed; [[!debbug 628843]]
+tracks fixing the hole in Debian's su. An upgrade is a must for any
+sites that have `ikiwiki-update-wikilist` installed suid (not the default),
+and whose admins run `ikiwiki-mass-rebuild`.
