| CVE-2019-7167 | 1 Z.cash | 1 Zcash | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Zcash, before the Sapling network upgrade (2018-10-28), had a counterfeiting vulnerability. A key-generation process, during evaluation of polynomials related to a to-be-proven statement, produced certain bypass elements. Availability of these elements allowed a cheating prover to bypass a consistency check, and consequently transform the proof of one statement into an ostensibly valid proof of a different statement, thereby breaking the soundness of the proof system. This misled the original Sprout zk-SNARK verifier into accepting the correctness of a transaction. | |||||
| CVE-2019-16930 | 1 Z.cash | 1 Zcash | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Zcashd in Zcash before 2.0.7-3 allows discovery of the IP address of a full node that owns a shielded address, related to mishandling of exceptions during deserialization of note plaintexts. This affects anyone who has disclosed their zaddr to a third party. | |||||
