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...

Keys generated with PGP5i batch mode do not contain sufficient randomness on systems that use /dev/random

Overview Under certain circumstances, PGP v5.0 generates keys that are not sufficiently random, which may allow an attacker to predict keys and, hence, recover information encrypted with that key. Description Generating Randomness in PGP Keys In order to generate cryptographically secure keys, PG...
