July 2017 Summaries

The PHP programming language is frequently updated to address critical security issues in its core, but many websites still run on outdated versions due to various reasons such as complexity or legacy obligations. Even with secure coding practices, the PHP interpreter itself can be vulnerable to memory corruption bugs that can lead to remote execution of arbitrary code and server compromise if exploited by an attacker through a PHP application's built-in features. Security researchers have identified numerous critical vulnerabilities in PHP's core over the years, including a $20,000 bug bounty for a use-after-free vulnerability in PHP's garbage collector. Staying ahead of these updates and applying security patches is crucial to fully protect applications against adversaries.
