Critical Cybersecurity Alerts: Linux, Python, PHP2Shell

Three separate critical vulnerabilities are in active exploitation: Linux has two unpatched 9.0/10 severity flaws allowing unauthenticated server takeover, Python's certificate authority was compromised with 8 keys exposed, and PHP2Shell saw millions of exploit attempts within hours of disclosure.

What we know

An account on X broke news of two Linux kernel vulnerabilities rated 9.0/10 with no official patches yet, one enabling unauthenticated server control; retweeted by another account on X. Another account on X amplified the Python CA compromise: 8 certificate authority keys were exposed (each a number below 256), potentially allowing attackers to intercept HTTPS connections to python.org and PyPI. Another account on X highlighted Cloudflare data showing PHP2Shell went from thousands of exploit attempts pre-announcement to millions within 2 hours post-disclosure. Another account on X noted only ~11% of exposed P2PShell services globally have been patched. Japan's Finance Minister commented that Japanese financial institutions had handled the PHP issue 'relatively smoothly'. Another account on X offered a pithy take: 'If your company refers to engineers as the IT department, you were already breached last week.'
