CVE-2020-12399

NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys. This vulnerability affects Thunderbird 68.9.0, Firefox 77, and Firefox ESR 68.9...

Improper uniqueness verification of signature threshold

The tough library, prior to 0.7.1, does not properly verify the uniqueness of keys in the signatures provided to meet the threshold of cryptographic signatures. It allows someone with access to a valid signing key to create multiple valid signatures in order to circumvent TUF requiring a minimum...

The Bouncy Castle Crypto APIs -- EC math vulnerability

The Bouncy Castle team reports:: Bouncy Castle BC Java before 1.66 has a timing issue within the EC math library that can expose information about the private key when an attacker is able to observe timing information for the generation of multiple deterministic ECDSA signatures...

CVE-2020-15091

TenderMint from version 0.33.0 and before version 0.33.6 allows block proposers to include signatures for the wrong block. This may happen naturally if you start a network, have it run for some time and restart it without changing chainID. A malicious block proposer even with a minimal amount of...

CVE-2020-15091

CVE-2020-15091 affects Tendermint up to v0.33.6: versions 0.33.0 through 0.33.5 allow a block proposer to include signatures for the wrong block, potentially halting the network. The root cause is signatures not guaranteed to correspond to the committed block, enabling a DoS condition where commi...

CVE-2020-15302

In Argent RecoveryManager before 0xdc350d09f71c48c5D22fBE2741e4d6A03970E192, the executeRecovery function does not require any signatures in the zero-guardian case, which allows attackers to cause a denial of service locking or a takeover...

Incorrect Signature Validation

jsrsasign uses an incorrect signature validation. It is possible because its RSASSA-PSS RSA-PSS implementation has a flaw which accepts manipulated/modified signatures as valid signatures by prepending '\0' bytes to a signature and also allows an attacker to send multiple valid signatures to...

CVE-2020-14966

An issue was discovered in the jsrsasign package through 8.0.18 for Node.js. It allows a malleability in ECDSA signatures by not checking overflows in the length of a sequence and '0' characters appended or prepended to an integer. The modified signatures are verified as valid. This could have a...
