Q: How to self-check? (Features/Scanning)

🔎 **Self-Check**: 1. Scan for OpenSSL versions < 0.9.8y or < 1.0.0m. 2. Check if **anonymous ECDH** ciphers are enabled. 3. Use scanners detecting null pointer dereferences in SSL handshakes. 🛡️

Q: Is it fixed officially? (Patch/Mitigation)

✅ **Fixed**: **Yes**. 🩹 **Patch**: Upgrade to OpenSSL **1.0.0m** or later. 📜 **Advisories**: Confirmed by VMware, Apple, and Mandriva. Update immediately! 🚀

Q: What if no patch? (Workaround)

🛡️ **No Patch Workaround**: 1. **Disable** anonymous ECDH cipher suites. 2. Remove `ECDH` ciphers with `NULL` authentication from config. 3. Restrict SSL/TLS protocols if possible. 🚫

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **High**. ⚡ **Priority**: Critical for systems using anonymous ECDH. 📅 **Published**: June 2014. Legacy systems still at risk. Patch now! ⏳

Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: A critical flaw in OpenSSL's `ssl3_send_client_key_exchange` function.
💥 **Consequences**: Causes **Denial of Service (DoS)**.…

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🔍 **Root Cause**: Logic error in `s3_clnt.c`.
⚠️ **Flaw**: Improper handling when using **anonymous ECDH cipher suites**. This leads to a **null pointer dereference** (CWE-476 implied).

Question 3

Who is affected? (Versions/Components)

Accepted Answer

📦 **Affected Versions**:
• OpenSSL **0.9.8y** and earlier
• OpenSSL **1.0.0** versions prior to **1.0.0m**
🌐 **Component**: The core OpenSSL cryptographic library.

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

🕵️ **Attacker Action**: Remote exploitation.
📉 **Impact**: **DoS** only. No data theft or privilege escalation mentioned. The goal is to **crash the client** via null pointer dereference. 📉

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

🔓 **Threshold**: **Low**.
🌐 **Auth**: **Remote** exploitation possible.
⚙️ **Config**: Requires use of **anonymous ECDH cipher suites**. If enabled, no authentication needed to trigger the crash.

Question 6

Is there a public Exp? (PoC/Wild Exploitation)

Accepted Answer

💻 **Public Exp**: **Yes**.
🔗 **PoC**: Available on GitHub (`hshivhare67/OpenSSL_1.0.1g_CVE-2014-3470`).
🔥 **Status**: Proof-of-concept exists for testing.

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔎 **Self-Check**:
1. Scan for OpenSSL versions < 0.9.8y or < 1.0.0m.
2. Check if **anonymous ECDH** ciphers are enabled.
3. Use scanners detecting null pointer dereferences in SSL handshakes. 🛡️

Question 8

Is it fixed officially? (Patch/Mitigation)

Accepted Answer

✅ **Fixed**: **Yes**.
🩹 **Patch**: Upgrade to OpenSSL **1.0.0m** or later.
📜 **Advisories**: Confirmed by VMware, Apple, and Mandriva. Update immediately! 🚀

Question 9

What if no patch? (Workaround)

Accepted Answer

🛡️ **No Patch Workaround**:
1. **Disable** anonymous ECDH cipher suites.
2. Remove `ECDH` ciphers with `NULL` authentication from config.
3. Restrict SSL/TLS protocols if possible. 🚫

Question 10

Is it urgent? (Priority Suggestion)

Accepted Answer

🔥 **Urgency**: **High**.
⚡ **Priority**: Critical for systems using anonymous ECDH.
📅 **Published**: June 2014. Legacy systems still at risk. Patch now! ⏳
