Simon McVittie 1ae01a592f Do not recommend mimetype(image/*)
Not all image file types are safe for general use: in particular,
image/svg+xml is known to be vulnerable to CVE-2016-3714 under some
ImageMagick configurations.

Joey Hess 21b9b9e306 update test suite for svg passthrough by img directive
Remove build dependency libmagickcore-6.q16-2-extra which was only there
for this test.

Simon McVittie 984ba82f1b img: Add back support for SVG images, bypassing ImageMagick and simply passing the SVG through to the browser
SVG scaling by img directives has subtly changed; where before size=wxh
would preserve aspect ratio, this cannot be done when passing them through
and so specifying both a width and height can change the SVG's aspect
ratio.

(This patch looks significantly more complex than it was, because a large
block of code had to be indented.)

[smcv: drop trailing whitespace, fix some spelling]

Simon McVittie 170cd41489 img: check magic number before giving common formats to ImageMagick
This mitigates CVE-2016-3714 and similar vulnerabilities by
avoiding passing obviously-wrong input to ImageMagick decoders.

Simon McVittie 545a7bbbf0 img: restrict to JPEG, PNG and GIF images by default
This mitigates CVE-2016-3714. Wiki administrators who know that they
have prevented arbitrary code execution via other formats can re-enable
the other formats if desired.
2016-05-05 23:43:50 +01:00
Simon McVittie 54a9f8d07d img: force common Web formats to be interpreted according to extension
A site administrator might unwisely set allowed_attachments to
something like '*.jpg or *.png'; if they do, an attacker could attach,
for example, a SVG file named attachment.jpg.

This mitigates CVE-2016-3714.

Simon McVittie 32ef584dc5 HTML-escape error messages (OVE-20160505-0012)
The instance in cgierror() is a potential cross-site scripting attack,
because an attacker could conceivably cause some module to raise an
exception that includes attacker-supplied HTML in its message, for
example via a crafted filename. (OVE-20160505-0012)

The instances in preprocess() is just correctness. It is not a
cross-site scripting attack, because an attacker could equally well
write the desired HTML themselves; the sanitize hook is what
protects us from cross-site scripting here.
