This prevents exploitation of any ImageMagick SVG coder + vulnerabilities. (joeyh) + - Do not resize image formats other than JPEG, PNG, GIF unless + specifically configured to do so. This prevents exploitation + of any vulnerabilities in less common coders, such as MVG. (smcv) + - Do not resize JPEG, PNG, GIF, PDF images if their extensions do + not match their "magic numbers", because wiki admins might try to + restrict attachments by extension, but ImageMagick can base its + choice of coder on the magic number. Explicitly force the + obvious ImageMagick coder to be used. (smcv) + * Minor non-security changes resulting from that update, since + reverting them seems higher-risk than keeping them: + - Add PDF support, disabled by the above changes unless specifically + configured (chrysn) + - Only render one frame or page from animated GIF or multi-page PDF + (chrysn) + - Do not distort aspect ratio when resizing small images (chrysn) + - Use data: URLs to embed images in page previews (chrysn) + - Raise an error if the image's size cannot be determined (chrysn) + - Handle filenames containing a colon correctly (smcv) + * Add t/img.t regression test also taken from version 3.20160506 + (chrysn, joeyh, schmonz, smcv) + * debian/tests: add metadata to run the img test as an autopkgtest -- Simon McVittie Sun, 08 May 2016 15:33:51 +0100
