Unity is one of the most popular game engines. It helps create many excellent cross-platform projects. It's been 4 years since the last time we checked Unity's source code. Time has come ag…

Researchers from the University of Cambridge described a technique that allows inserting invisible adversarial code in the reviewed source texts. The attack (CVE-2021-42574) is called Trojan Source...

Meet the latest PVS-Studio release — 7.18. This article will tell you about how we improved the analysis of modern C++, the search of security defects from the OWASP Top 10 list, and a new …

We present a new type of attack in which source code is maliciously encoded so that it appears different to a compiler and to the human eye. This attack exploits subtleties in text-encoding…

The PVS-Studio static analyzer encompasses the symbolic execution mechanism. And today we have a great opportunity to demonstrate how this feature helps find errors.

Vulnerabilities produce enormous reputational and financial risks. That′s why many companies are fascinated by security and desire to build a secure development life cycle (SSDLC). So, toda…

Some developers may be dismissive of checks: they deliberately do not check whether the malloc function allocated memory or not. Their reasoning is simple — they think that there will be enough...

Use static analysis regularly, not just before releases... The earlier you find errors, the cheaper they are to fix... You probably heard this a hundred times. Today we'll answer the Why? q…

The PVS-Studio static analyzer is constantly evolving. We enhance various mechanisms, integrate the analyzer with game engines, IDEs, CI/CD instruments, and other systems and services. A fe…

Related variables are one of the main problems of static analysis. This article covers this topic and describes how PVS-Studio developers are fighting false positives caused by different re…

Welcome all developers and everyone who commiserate. Everyone commented their code at least once — that′s for sure. Was it your code or someone else′s? Were these comments useful? Or were they made...

Hello! My name is Alexander and I work as a microcontroller developer.

The cost of making a video game has increased over the years. Game development is becoming increasingly complex, the code base is getting larger as well. It′s getting harder for developers …

We happen to write code for IoT stuff related to electricity, like car charging stations. Since hardware resources are usually sufficient, our main goal is not to save on every byte possibl…

Bitwarden is an open-source password management service. The software helps generate and manage unique passwords. Will PVS-Studio find errors in such a project?

The number of bugs in our bug list has exceeded 15000. This is exactly the number of bugs found by the PVS-Studio team in various open-source projects. Most excitingly, our bug collection i…

PVS-Studio can hide repeated warnings. The analyzer allows you to set baseline, which makes it easy to implement static analysis in legacy projects. Should we provide these features for thi…

Like any other tool, POSIX signals have their own rules on how to use them wisely, securely, and safely. Programming language standards, man pages and the POSIX standard itself have described POSIX...

Nowadays system resources are widely available. Ordinary high-level application software developers have to follow minimum system requirements. So, don′t expect them to optimize the code to…

A long time ago, I performed technical interviews on a regular basis — I was recruiting candidates for the position of a programmer in a company. I had a simple, clear, and smart recruitmen…
