allowing an attacker to carry out cross-site scripting by directing a
user to a URL that would result in a crafted ikiwiki error message. This
was discovered on 4 May by the ikiwiki developers, and the fixed version
-3.20160506 was released on 6 May. An upgrade is recommended for sites using
-the CGI.

## ImageMagick CVE-2016–3714 ("ImageTragick")
-ikiwiki 3.20160506 attempts to mitigate [[!cve CVE-2016-3714]] and any
+ikiwiki 3.20160506 and 3.20141016.3 attempt to mitigate
+[[!cve CVE-2016-3714]], and any
future ImageMagick vulnerabilities that resemble it, by restricting the
image formats that the [[ikiwiki/directive/img]] directive is willing to
resize. An upgrade is recommended for sites where an untrusted user is
able to attach images. Upgrading ImageMagick to a version where
CVE-2016-3714 has been fixed is also recommended, but at the time of
writing no such version is available.

+## Perl CVE-2016-1238 (current working directory in search path)
+
+ikiwiki 3.20160728 attempts to mitigate [[!cve CVE-2016-1238]] by
+removing `'.'` from the Perl library search path. An attacker with write
+access to ikiwiki's current working directory could potentially use this
+vulnerability to execute arbitrary Perl code. An upgrade is recommended
+for sites where an untrusted user is able to attach files with arbitrary
+names and/or run a setuid ikiwiki wrapper with a working directory of
+their choice.
