Thank you. To be clear, I don&#x27;t mean that as a criticism of the developers, who as the parent points out do very useful work and do it for free. But I feel that it&#x27;s important to have an objective look at the current shortcomings in the state of 7-zip security, both in order to understand what needs to be done to fix it, and in order to warn current users until those issues are fixed.<p>7-zip is a widely popular basic utility, like a web browser. A flaw in 7-zip is very serious, because as I pointed out elsewhere simply opening a .zip file will allow an attacker to exploit it. And while there is a strong security culture among web browser developers, 7-zip doesn&#x27;t seem to have that culture (yet).<p>There is certainly a massive budget and manpower difference, but a lack of mention of security fixes in the changelog and a lack of hashes isn&#x27;t a manpower issue, it&#x27;s a culture issue.<p>As a side note, compromise of a developer&#x27;s machine is a big deal in my opinion: it could be easy for a criminal entity to slip in a tiny change in a large patch that introduces a vulnerability; and depending on how builds are performed, a criminal could patch the final .exe with no visible change to the source code. These are tailored attacks, but for a very widely distributed program it would easily be worth the criminal&#x27;s time.
