CVE-2020-1026

The CVE-2020-1026 issue affects the MSR JavaScript Cryptography Library’s ECC implementation. It results from multiple bugs in ECC code, enabling an attacker to potentially leak a server’s private ECC key (key leakage attack) or craft an invalid ECDSA signature that passes as valid. The vulnerabi...

MSR JavaScript Cryptography Library Security Feature Bypass Vulnerability

A Security Feature Bypass vulnerability exists in the MSR JavaScript Cryptography Library that is caused by multiple bugs in the library’s Elliptic Curve Cryptography ECC implementation. An attacker could potentially abuse these bugs to learn information about a server’s private ECC key a key...

wolfssl

This is a collection of files related to the wolfSSL library, a cryptographic library for embedded systems. The library is designed to be compatible with Arduino projects and provides a range of cryptographic functions, including SSL/TLS, RSA, and AES. The files include: IDE/ARDUINO/README.md: A...

Arbitrary Code Execution

ntpd is vulnerable to arbitrary code execution. A buffer overflow flaw was discovered in the ntpd daemon's NTPv4 authentication code. If ntpd was configured to use public key cryptography for NTP packet authentication, a remote attacker could use this flaw to send a specially-crafted request pack...

CVE-2018-21058

An issue was discovered on Samsung mobile devices with N7.0, O8.0 exynos7420 or Exynos 8890/8996 chipsets software. Cache attacks can occur against the Keymaster AES-GCM implementation because T-Tables are used; the Cryptography Extension CE is not used. The Samsung ID is SVE-2018-12761 September...

CVE-2019-11840

An issue was discovered in supplementary Go cryptography libraries, aka golang-googlecode-go-crypto, before 2019-03-20. A flaw was found in the amd64 implementation of golang.org/x/crypto/salsa20 and golang.org/x/crypto/salsa20/salsa. If more than 256 GiB of keystream is generated, or if the...

CVE-2020-11501

GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 2018-07-16 because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks...
