Summary
Researchers at cybersecurity firm Qualys have identified a critical vulnerability in the widely used OpenSSH secure communications protocol, named "regreSSHion". This flaw, affecting nearly 14 million instances, could allow attackers to gain full access to systems and bypass firewalls, though it is challenging to exploit under typical conditions. The vulnerability, CVE-2024-6387, was re-introduced in 2020 after being fixed nearly a decade ago. While experts caution against overhyping the severity, they emphasize the importance of zero trust and mitigating risks. The bug primarily impacts older, 32-bit Linux systems and highlights the need for continued efforts toward using memory-safe languages to secure open-source ecosystems.
