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...

TLS DHE_EXPORT Information Disclosure (MS15-055; CVE-2015-1716; CVE-2015-4000)

An information disclosure vulnerability exists in multiple implementations of TLS 1.2 and earlier, when Ephemeral Diffie-Hellman cipher suites including their EXPORT versions are used. It is possible to downgrade a DHE cipher to a DHEEXPORT cipher, which can be broken, and thereby perform a...

MGASA-2015-0246 Updated openssl package fixes security vulnerabilities

A vulnerability in the TLS protocol allows a man-in-the-middle attacker to downgrade vulnerable TLS connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography. This vulnerability is known as Logjam CVE-2015-4000. When processing an ECParameters structure OpenSSL...
