GLSA-201606-12 : libssh and libssh2: Multiple vulnerabilities
The remote host is affected by the vulnerability described in GLSA-201606-12 libssh and libssh2: Multiple vulnerabilities libssh and libssh2 both have a bits/bytes confusion bug and generate an abnormaly short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange...
libssh and libssh2: Multiple vulnerabilities
Background libssh is a mulitplatform C library implementing the SSHv2 and SSHv1 protocol on client and server side. Description libssh and libssh2 both have a bits/bytes confusion bug and generate an abnormaly short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key...

SUSE-SU-2016:1457-1 Security update for cyrus-imapd
Previous versions of cyrus-imapd would not allow its users to disable old protocols like SSLv1 and SSLv2 that are unsafe due to various known attacks like BEAST and POODLE. https://bugzilla.cyrusimap.org/showbug.cgi?id=3867 remedies this issue by adding the configuration option 'tlsversions' to...
Botan weak encryption vulnerability
Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A weak cryptographic vulnerability in the Miller-Rabin prime test in Botan versions prior to 1.10.8 and 1.11.x prior to 1.11.9 stems from the program failing to properly use a single...
UBUNTU-CVE-2014-9742
The Miller-Rabin primality check in Botan before 1.10.8 and 1.11.x before 1.11.9 improperly uses a single random base, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a DH group...

USN-2959-1 openssl vulnerabilities
Huzaifa Sidhpurwala, Hanno Böck, and David Benjamin discovered that OpenSSL incorrectly handled memory when decoding ASN.1 structures. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. CVE-2016-2108 Juraj...
nss: Use-after-free in NSS during SSL connections in low memory (MFSA 2016-15)
A use-after-free flaw was found in the way NSS handled DHE Diffie–Hellman key exchange and ECDHE Elliptic Curve Diffie-Hellman key exchange handshake messages. A remote attacker could send a specially crafted handshake message that, when parsed by an application linked against NSS, would cause th...
