LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks
A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange for both export and non-export grade cipher suites. An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lea...
Mozilla Reduces Threat of Export-Grade Crypto to Firefox
Logjam was one of several downgrade attacks discovered in the last 18 months that could theoretically allow a resourced attacker to take advantage of lingering export-grade cryptography to read and modify data over a supposedly secure connection. While the severity of this particular attack again...

Export-Grade Crypto Patching Improves
LAS VEGAS – The FREAK, LOGJAM and DROWN attacks of the last 17 months weren’t just the work of academics and security researchers who found a cool way to unmask encrypted traffic. They were ugly reminders of the Crypto Wars of the 1990s and why export-grade cryptography and intentional encryption...
Important: openssl098e
Issue Overview: A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled. CVE-2015-02...
DROWN Flaw Illustrates Dangers of Intentionally Weak Crypto
Calls for encryption backdoors that date back to the 1990s are coming back to haunt the industry 20 years later with DROWN, security experts say. The flaw that researchers found with DROWN center around the fact that during the so called Crypto Wars of the 1990s President Bill Clinton’s...
DROWN Flaw Opens 33 Percent Of HTTPS Connections To Attack
Researchers revealed a massive transport layer security TLS vulnerability today that leaves millions of Internet users vulnerable to an attack that could expose passwords, credit card numbers and financial data. OpenSSL and others are urging companies to patch their web servers or risk exposure t...
