Debian Security Advisory DSA 3488-1 (libssh - security update)

Aris Adamantiadis discovered that libssh, a tiny C SSH library, incorrectly generated a short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. The resulting secret is 128 bits long, instead of the recommended sizes of 1024 and 2048 bits respectively...

FreeBSD : libssh -- weak Diffie-Hellman secret generation (6b3591ea-e2d2-11e5-a6be-5453ed2e2b49)

Andreas Schneider reports : libssh versions 0.1 and above have a bits/bytes confusion bug and generate an abnormally short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. The resulting secret is 128 bits long, instead of the recommended sizes of 102...

Debian DLA-425-1 : libssh security update

Aris Adamantiadis of the libssh team discovered that libssh, an SSH2 protocol implementation used by many applications, did not generate sufficiently long Diffie-Hellman secrets. This vulnerability could be exploited by an eavesdropper to decrypt and to intercept SSH sessions. For the oldoldstabl...

FreeBSD : socat -- diffie hellman parameter was not prime (a52a7172-c92e-11e5-96d6-14dae9d210b8)

socat reports : In the OpenSSL address implementation the hard-coded 1024 bit DH p parameter was not prime. The effective cryptographic strength of a key exchange using these parameters was weaker than the one one could get by using a prime p. Moreover, since there is no indication of how these...
