Hybrid Quantum Security for IPsec

Quantum Key Distribution QKD offers information-theoretic security against quantum computing threats, but integrating QKD into existing security protocols remains an unsolved challenge due to fundamental mismatches between pre-distributed quantum keys and computational key exchange paradigms. Thi...

OESA-2025-1775 python-cryptography security update

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Security Fixes: A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lea...

On Key Exchange Protocol Based on Two-Side Multiplication Action

We present a cryptanalysis of a key exchange protocol based on the digital semiring. For this purpose, we find the maximal solution of a linear system over such semiring, and use the properties of circulant matrix to demonstrate that the protocol is vulnerable. Specifically, we provide an efficie...

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...

Important: amazon-ssm-agent

Issue Overview: SSH servers which implement file transfer protocols are vulnerable to a denial of service attack from clients which complete the key exchange slowly, or not at all, causing pending content to be read into memory, but never transmitted. CVE-2025-22869 Affected Packages:...

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...
