CVE-2019-7167

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...

CVE-2019-7167

CVE-2019-7167 concerns Zcash prior to the Sapling upgrade (2018-10-28), where a flaw in the key-generation process during polynomial evaluation allowed bypass elements to defeat a consistency check. This could enable a cheating prover to transform a proof of one statement into a seemingly valid p...
