CVE-2019-16753: Decentralized Anonymous Payment System Project Decentralized Anonymous Payment System

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

An issue was discovered in Decentralized Anonymous Payment System (DAPS) through 2019-08-26. The content to be signed is composed of a representation of strings, rather than being composed of their binary representations. This is a weak signature scheme design that would allow the reuse of signatures in some cases (or even the reuse of signatures, intended for one type of message, for another type). This also affects Private Instant Verified Transactions (PIVX) through 3.4.0.

Affected products

• Decentralized Anonymous Payment System Project Decentralized Anonymous Payment System: up to and including 2019-08-26
• Pivx Private Instant Verified Transactions: up to and including 3.4.0
