Denial Of Service (DoS)

OpenSSL is vulnerable to denial of service DoS attacks. A malicious user can pass a malicious Diffie-Hellman ServerKeyExchange message to the system to cause a segmentation fault that can lead to the system crashing...

Information Disclosure

OpenSSL is vulnerable to information disclosure. The library contains a carry propagation bug during the montgomery squaring procedure. This makes it easier for a malicious user to obtain sensitive private key information from the Diffie-Hellman and Diffie-Hellman Ephemereal Ciphersuites...

UBUNTU-CVE-2016-2217

The OpenSSL address implementation in Socat 1.7.3.0 and 2.0.0-b8 does not use a prime number for the DH, which makes it easier for remote attackers to obtain the shared secret...

DEBIAN-CVE-2016-2217

The OpenSSL address implementation in Socat 1.7.3.0 and 2.0.0-b8 does not use a prime number for the DH, which makes it easier for remote attackers to obtain the shared secret...

Weak Diffie-Hellman Handshake Due To Truncated Secret Length

libssh2 is vulnerable to weak handshakes. The vulnerability happens because diffiehellmansha256 function in kex.c in libssh2 generates secret key of length 128 or 256 bits instead of 1023 or 2047 bits, allowing the attackers to intercept or decrypt SSH sessions using bits/bytes confusion bug...

scalarmult() vulnerable to degenerate public keys

The scalarmult function included in previous versions of this crate accepted all-zero public keys, for which the resulting Diffie-Hellman shared secret will always be zero regardless of the private key used. This issue was fixed by checking for this class of keys and rejecting them if they are us...

RUSTSEC-2017-0001 scalarmult() vulnerable to degenerate public keys

The scalarmult function included in previous versions of this crate accepted all-zero public keys, for which the resulting Diffie-Hellman shared secret will always be zero regardless of the private key used. This issue was fixed by checking for this class of keys and rejecting them if they are us...

UBUNTU-CVE-2017-3732

There is a carry propagating bug in the x8664 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed...

UBUNTU-CVE-2016-6271

The Bzrtp library aka libbzrtp 1.0.x before 1.0.4 allows man-in-the-middle attackers to conduct spoofing attacks by leveraging a missing HVI check on DHPart2 packet reception...

Carry Propagation

bouncycastle is vulnerable to carry propagation bugs. This bug caused mathematical miscalculations during static Elliptic Curve Diffie Hellman which in rare cases for it to miscalculate elliptic curve scalar multiplication. This allows a malicious user in certain cases to obtain the key...

Unsafe Encryption Scheme

bouncycastle unsafely uses an electronic code book ECB when using the Diffie-Hellman Integrated Encryption Scheme DHIES. ECB is known to be unsafe, particularly against replay attacks...

Partial Key Validation

bouncycastle is vulnerable to partial key validation. The library doesn't fully validate the other parties' Diffie-Hellman key, meaning that invalid keys can reveal information about the other parties' private key when static Diffie-Hellman is used...

Ubuntu 14.04 LTS / 16.04 LTS : NSS vulnerabilities (USN-3163-1)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3163-1 advisory. It was discovered that NSS incorrectly handled certain invalid Diffie-Hellman keys. A remote attacker could possibly use this flaw to cause N...

USN-3163-1: NSS vulnerabilities

It was discovered that NSS incorrectly handled certain invalid Diffie-Hellman keys. A remote attacker could possibly use this flaw to cause NSS to crash, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. CVE-2016-5285 Hubert Kari...

MGASA-2016-0392 Updated libssh2 packages fix security vulnerability

Andreas Schneider reported that libssh2 passes the number of bytes to a function that expects number of bits during the SSHv2 handshake when libssh2 is to get a suitable value for 'group order' in the Diffie-Hellman negotiation. This weakens significantly the handshake security, potentially...
