The Elliptic package 6.5.7 for Node.js, in its for ECDSA implementation, does not correctly verify valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an truncateToN anomaly. This leads to valid signatures being rejected. Legitimate transactions or communications may be incorrectly flagged as invalid.

IBM Cognos Analytics Mobile 1.1 for iOS application could allow an attacker to reverse engineer the codebase to gain knowledge about the programming technique, interface, class definitions, algorithms and functions used due to weak obfuscation.
