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...

Mbed TLS -- Side channel attack on ECDSA

Manuel Pégourié-Gonnard reports: An attacker with access to precise enough timing and memory access information typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world can fully recover an ECDSA private key after observing a number of signature...

The vulnerability of the Python ECDSA cryptographic library, related to improper verification of the cryptographic signature, allows a perpetrator to compromise the confidentiality and integrity of the protected information.

The vulnerability of the Python ECDSA cryptographic library is related to improper verification of the cryptographic signature. Exploiting this vulnerability could allow a malicious actor, operating remotely, to compromise the confidentiality and integrity of the protected information...

Timing Attack

jsrsasign is vulnerable to timing attack. A timing attack can be performed to discover the private key due to the usage of an unsafe method for ECDSA key generation and signing in the signHex function...

Timing Attack

Overview Versions of jsrsasign are vulnerable to Timing Attacks. The signHex function uses a timing-unsafe method for ECDSA key generation and signing. This leaks the length of the scalar, which attackers may use to brute-force the private key. Timing attacks can be used to increase the efficienc...

GHSA-8QXJ-F9RH-9FG2 Improper Verification of Cryptographic Signature in Pure-Python ECDSA

A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable...

ROHNP: Key Extraction Side Channel in Multiple Crypto Libraries

Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. T...

Amazon Linux 2 : openssl (ALAS-2020-1406)

The version of openssl installed on the remote host is prior to 1.0.2k-19. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1406 advisory. Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths...

Security Bulletin: Multiple vulnerabilities in OpenSSL affect IBM Integration Bus , IBM App Connect and WebSphere Message Broker

Summary Multiple vulnerabilities in OpenSSL affect IBM Integration Bus , IBM App Connect and WebSphere Message Broker. The DataDirect ODBC Drivers used by IBM App Connect , IBM Integration Bus and WebSphere Message Broker have addressed the applicable CVEs. Vulnerability Details CVEID:...

Important: openssl

Issue Overview: Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters instead of using a named curve. In those cases it is possible that such a grou...
