OpenSSL Code Issue Vulnerability
OpenSSL is an open source capable general-purpose cryptographic library from the OpenSSL team that implements the Secure Sockets Layer SSLv2/v3 and Secure Transport Layer TLSv1 protocols. It supports a variety of cryptographic algorithms, including symmetric ciphers, hashing algorithms, secure...
USN-6435-2: OpenSSL vulnerabilities
USN-6435-1 fixed vulnerabilities in OpenSSL. This update provides the corresponding updates for Ubuntu 20.04 LTS. Original advisory details: It was discovered that OpenSSL incorrectly handled excessively large Diffie-Hellman parameters. An attacker could possibly use this issue to cause a denial ...
USN-6435-2 openssl vulnerabilities
USN-6435-1 fixed vulnerabilities in OpenSSL. This update provides the corresponding updates for Ubuntu 20.04 LTS. Original advisory details: It was discovered that OpenSSL incorrectly handled excessively large Diffie-Hellman parameters. An attacker could possibly use this issue to cause a denial ...
Why We Don’t Generate Elliptic Curves Every Day
With all the talk recently of how the NIST curve parameters were selected, a reasonable observer could wonder why we all use the same curves instead of generating them along with keys, like we do for Diffie-Hellman parameters. You might have memories of waiting around for openssl dhparam to run a...
OpenSSL: Excessive time spent checking DH q parameter value
A vulnerability was found in OpenSSL. This security issue occurs because the applications that use the DHcheck, DHcheckex, or EVPPKEYparamcheck functions to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an...

nodejs: DiffieHellman do not generate keys after setting a private key
A vulnerability has been identified in the Node.js, where a generateKeys API function returned from crypto.createDiffieHellman only generates missing or outdated keys, that is, it only generates a private key if none has been set yet...
Mbed TLS Code Execution
The vulnerability of the implementation of TLS and SSL software developed by Mbed TLS is related to the possibility of buffer overflow attacks. Exploiting this vulnerability allows a malicious actor to execute arbitrary code remotely by sending specially crafted open ECDH or FFDH keys...
PT-2023-5756 · Mbed Tls +1 · Mbed Tls +1
Name of the Vulnerable Software and Affected Versions: Mbed TLS versions 3.2.x through 3.4.x Description: The issue is related to a buffer overflow in Mbed TLS, which can lead to remote code execution. This occurs due to a heap-based buffer overflow vulnerability in the implementation of TLS and...

Siemens LOGO! CMR and SIMATIC RTU 3000 Incorrect Calculation of Buffer Size (CVE-2020-36475)
An issue was discovered in Mbed TLS before 2.25.0 and before 2.16.9 LTS and before 2.7.18 LTS. The calculations performed by mbedtlsmpiexpmod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie- Hellman key pairs. This plugin only works...
