Libtiff 4.0.9 has been released. According to the email announcing it:
A great many security improvements have been implemented by Even Rouault.
Much thanks to OSS Fuzz, team OWL337, Roger Leigh, and of course Even Rouault.
Obligatory reminder: Don’t download from libtiff dot org. It’s many years out of date.
An Open Preservation Foundation webinar, “Putting JHOVE to the acid test: A PDF test-set for well-formedness validation in JHOVE,” will be held on November 21, 10 AM GMT (that’s 11 AM in Central Europe and a ludicrous 5 AM or earlier in the US).
Popular Science has an article, “How to convert any file to any format.” The title overreaches, but the article actually isn’t too bad. It’s addressed at the ordinary user, not the file format specialist, so it wouldn’t be appropriate to complain too much that it has more breadth than depth.
It starts by recommending using the application that created the file, and that’s certainly good advice. Even when formats are open standards, an app knows more about how it creates its own files than anyone else does. Its files might have bits of application-specific information.
