OpenSSL Patches High-Severity Denial-of-Service Bug

OpenSSL on Thursday patched three vulnerabilities in its latest update, and reminded users running version 1.0.1 of the cryptographic library that that security support will end Dec. 31. Of the three bugs, only one was rated high severity and could lead to OpenSSL crashes. Only OpenSSL 1.1.0 is...

The RFC 5114 saga

Back in January I posed a question "to the Internet": What the heck is RFC 5114? It looks like a lot happened since then around it. I would like to use this post to recollect some of the stuff around RFC5114 . Chapter 0: October 2007 RFC5114 draft was submitted to the IETF . Chapter I: January 20...

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...

Debian Security Advisory DSA 3688-1 (nss - security update)

Several vulnerabilities were discovered in NSS, the cryptography library developed by the Mozilla project. CVE-2015-4000 David Adrian et al. reported that it may be feasible to attack Diffie-Hellman-based cipher suites in certain circumstances, compromising the confidentiality and integrity of da...

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...

SSH-Weak-DH - SSH Weak Diffie-Hellman Group Identification Tool

This tool establishes SSH connections to a server, thereby enumerating through various client configurations, in order to determine whether the server allows a Diffie-Hellman DH key exchange based on a weak group. We hope that our tool will be useful to check SSH servers for weak DH key exchange...
