CVE-2025-8556

A flaw was found in CIRCL's implementation of the FourQ elliptic curve. This vulnerability allows an attacker to compromise session security via low-order point injection and incorrect point validation during Diffie-Hellman key exchange. Mitigation Mitigation for this issue is either not availabl...

TencentOS Server 4: openssl (TSSA-2024:0532)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0532 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities...

Low-order Point Validation Failure

github.com/cloudflare/circl is vulnerable to low-order point validation failure. The vulnerability is due to the failure to validate user-supplied low-order points during the Diffie-Hellman key exchange, which can allow attackers to force the identity point and compromise session security...

Improper Input Validation

Overview Affected versions of this package are vulnerable to Improper Input Validation due to the improper validation of user-supplied low-order points during the Diffie-Hellman key exchange process. An attacker can compromise session security by forcing the identity point. Additionally, incorrec...

CIRCL-Fourq: Missing and wrong validation can lead to incorrect results

Impact The CIRCL implementation of FourQ fails to validate user-supplied low-order points during Diffie-Hellman key exchange, potentially allowing attackers to force the identity point and compromise session security. Moreover, there is an incorrect point validation in ScalarMult can lead to...

The vulnerability of the Diffie-Hellman Key Exchange (DHE) protocol, which is related to uncontrolled resource consumption, allows a attacker to cause a service failure.

The vulnerability of the Diffie-Hellman Key Exchange DHE protocol is related to an uncontrolled consumption of resources. Exploiting this vulnerability could allow a malicious actor, operating remotely, to cause service interruptions...

CVE-2024-20069

In modem, there is a possible selection of less-secure algorithm during the VoWiFi IKE due to a missing DH downgrade check. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01286330; Iss...

CVE-2024-54847

An issue in CP Plus CP-VNR-3104 B3223P22C02424 allows attackers to access the Diffie-Hellman DH parameters and access sensitive data or execute a man-in-the-middle attack...

CVE-2023-28113

russh is a Rust SSH client and server library. Starting in version 0.34.0 and prior to versions 0.36.2 and 0.37.1, Diffie-Hellman key validation is insufficient, which can lead to insecure shared secrets and therefore breaks confidentiality. Connections between a russh client and server or those ...

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...

CVE-2002-20001

The Diffie-Hellman Key Agreement Protocol allows remote attackers from the client side to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a DHEat or DHEater attack. The client needs very little CPU resources...

kernel: nvmet-auth: assign dh_key to NULL after kfree_sensitive

In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: assign dhkey to NULL after kfreesensitive ctrl-dhkey might be used across multiple calls to nvmetsetupdhgroup for the same controller. So it's better to nullify it after release on error path in order to avoid double...

Linux Distros Unpatched Vulnerability : CVE-2024-41996

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers from the clie...
