SUSE CVE-2015-0837
The mpipowm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel Attack."...
SUSE CVE-2016-0702
The MODEXPCTIMECOPYFROMPREBUF function in crypto/bn/bnexp.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g does not properly consider cache-bank access times during modular exponentiation, which makes it easier for local users to discover RSA keys by running a crafted application on the...
SUSE CVE-2022-40735
The Diffie-Hellman Key Agreement Protocol allows use of long exponents that arguably make certain calculations unnecessarily expensive, because the 1996 van Oorschot and Wiener paper found that "appropriately short exponents" can be used when there are adequate subgroup constraints, and these sho...

Diffie-Hellman Key Agreement Protocol 资源管理错误漏洞
The Diffie-Hellman Key Agreement Protocol is a key negotiation protocol. It was originally described in Diffie and Hellman's seminal paper on public key cryptography. The key negotiation protocol allows Alice and Bob to exchange public key values and securely compute a shared key K based on...
Security Bulletin: IBM MQ and IBM WebSphere MQ are affected by Side channel attacks on modular exponentiation (CVE-2016-0702)
Summary IBM MQ and WebSphere MQ have addressed CVE-2016-0702 The GSKit cryptographic libraries supplied with MQ are impacted by the same issue described in the OpenSSL disclosure. Vulnerability Details CVEID: CVE-2016-0702 DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive...
Vulnerability of the Montgomery modular exponentiation function with constant time complexity in the OpenSSL and BoringSSL libraries, allowing attackers to execute arbitrary code.
The vulnerability of the Montgomery modular multiplication function with a constant time cost in the OpenSSL and BoringSSL libraries relates to the possibility of writing data beyond the buffer boundaries into memory. Exploiting this vulnerability allows an attacker to execute arbitrary code by...
GSD-2022-1002526 heap buffer overflow in OpenSSL version 3.0.4
In OpenSSL version 3.0.4 a heap buffer overflow exists in the AVX512 support that can be attacked via network resulting in code execution. This is reachable via four code paths: RSAZ 1024, RSAZ 512, Dual 1024 RSAZ, and Default constant-time Montgomery modular exponentiation. Please note this issu...
F5 Networks BIG-IP : Diffie-Hellman key agreement protocol weaknesses (K83120834)
The version of F5 Networks BIG-IP installed on the remote host is prior to 16.1.4 / 17.1.0. It is, therefore, affected by multiple vulnerabilities as referenced in the K83120834 advisory. The Diffie-Hellman Key Agreement Protocol allows remote attackers from the client side to send arbitrary...
CVE-2002-20001
CVE-2002-20001 describes a Diffie-Hellman key exchange weakness where a remote attacker (from the client side) can send non-public values to induce expensive server-side DHE modular-exponentiation, potentially impacting availability. The description specifies that the attack is most disruptive wh...
