-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 nCipher Security Advisory No. 12 Insecure Generation of Diffie-Hellman keys ------------------------------------------ Note ==== nCipher is publishing three advisories numbered 12, 13, and 14 simultaneously. You are advised to review all three before...
CVE-2006-1115: Undefined Security Weakness
nCipher HSM before 2.22.6, when generating a Diffie-Hellman public/private key pair without any specified DiscreteLogGroup parameters, chooses random parameters that could allow an attacker to crack the private key in significantly less time than a brute force attack...
Tor: Information disclosure
Background Tor is an implementation of second generation Onion Routing, a connection-oriented anonymizing communication service. Description The Diffie-Hellman implementation of Tor fails to verify the cryptographic strength of keys which are used during handshakes. Impact By setting up a malicio...
CVE-2005-2643
Tor 0.1.0.13 and earlier, and experimental versions 0.1.1.4-alpha and earlier, does not reject certain weak keys when using ephemeral Diffie-Hellman DH handshakes, which allows malicious Tor servers to obtain the keys that a client uses for other systems in the circuit...

tor -- diffie-hellman handshake flaw
A tor advisory reports Tor clients can completely loose anonymity, confidentiality, and data integrity if the first Tor server in their path is malicious. Specifically, if the Tor client chooses a malicious Tor server for her first hop in the circuit, that server can learn all the keys she...
