Multiple security vulnerabilities have been found in OpenEXR, command-line
tools and a library for the OpenEXR image format. Buffer overflows or
out-of-bound reads could lead to a denial of service (application crash) if a
malformed image file is processed.
Today I have some squid geopolitical news.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

This article talks about public land in the US that is completely surrounded by private land, which in some cases makes it inaccessible to the public. But there’s a hack:
Some hunters have long believed, however, that the publicly owned parcels on Elk Mountain can be legally reached using a practice called corner-crossing.
Corner-crossing can be visualized in terms of a checkerboard. Ever since the Westward Expansion, much of the Western United States has been divided into alternating squares of public and private land. Corner-crossers, like checker pieces, literally step from one public square to another in diagonal fashion, avoiding trespassing charges. The practice is neither legal nor illegal. Most states discourage it, but none ban it.
It’s an interesting ambiguity in the law: does checker trespass on white squares when it moves diagonally over black squares? But, of course, the legal battle isn’t really about that. It’s about the rights of property owners vs the rights of those who wish to walk on this otherwise-inaccessible public land.
This particular hack will be adjudicated in court. State court, I think, which means the answer might be different in different states. It’s not an example I discuss in my new book, but it’s similar to many I do discuss. It’s the act of adjudicating hacks that allows systems to evolve.

As ever, what matters most is not so much whether an organisation gets hit or not by a ransomware attack, but how well it handles the aftermath and recovery.
