1 News for ikiwiki 3.20160506:
3 To mitigate [[!cve CVE-2016-3714]] and similar ImageMagick security vulnerabilities,
4 the `[[!img]]` directive is now restricted to these common web formats by
6 * JPEG (`.jpg`, `.jpeg`)
10 (In particular, by default resizing PDF files is no longer allowed.)
11 Additionally, resized SVG files are displayed in the browser as SVG
12 instead of being converted to PNG.
13 If all users who can attach images are fully trusted, this restriction
14 can be removed with the new img\_allowed\_formats setup option.
15 See [[ikiwiki/directive/img]] for more details.

22 * Mitigate ImageMagick vulnerabilities such as CVE-2016-3714:
23 - img: force common Web formats to be interpreted according to extension,
24 so that "allowed\_attachments: '*.jpg'" does what one might expect
25 - img: restrict to JPEG, PNG and GIF images by default, again mitigating
26 CVE-2016-3714 and similar vulnerabilities
27 - img: check that the magic number matches what we would expect from
28 the extension before giving common formats to ImageMagick

32 * img: Add back support for SVG images, bypassing ImageMagick and
33 simply passing the SVG through to the browser, which is supported by all
34 commonly used browsers these days.
35 SVG scaling by img directives has subtly changed; where before
36 size=wxh would preserve aspect ratio, this cannot be done when passing
37 them through and so specifying both a width and height can change
38 the SVG's aspect ratio.
