Crafting regexes to avoid stack overflows
Due to the way regular expression matching is implemented in Java (and many other languages/libraries), matching a pattern may - depending on the regex - require stack space proportional to the length of the input. This means large inputs could cause the program to crash with a `StackOverflowException` when you try to use the regex.

Setting the right (regex) boundaries is important
Regular expressions pack a lot of power into terse little packages and unfortunately that introduces a lot of room for error. This post talks about regex boundaries, another feature that can lead to bugs when used incorrectly, and a rule of ours that can help you avoid such issues. it also covers about complexity and maintainability in regular expressions and our rule to help you find regular expressions that are too complex.

Code vulnerabilities put health records at risk
Recently, we discovered several code vulnerabilities in OpenEMR 5.0.2.1. A combination of these vulnerabilities allowed remote attackers to execute arbitrary system commands on any OpenEMR server that uses the Patient Portal component. This can lead to the compromise of sensitive patient data, or worse, to a compromise of critical infrastructure.

Winning the race against TOCTOU vulnerabilities in C & C++
Security is an eternal race between the techniques and technologies of attackers and those of the defenders. Today, I'm proud to announce a step forward for defenders with a new rule to detect a literal race condition: TOCTOU (or TOCTTOU) vulnerabilities, known in long-form as Time Of Check (to) Time Of Use.
