CVE-2019-15545: Improper Verification of Cryptographic Signature

An issue was discovered in the libp2p-core crate before 0.8.1 for Rust. Attackers can spoof ed25519 signatures...

Using Ed25519 signing keys for encryption

@Benjojo12 and I are building an encryption tool that will also support SSH keys as recipients, because everyone effectively already publishes their SSH public keys on GitHub. For RSA keys, this is dangerous but straightforward: a PKCS1 v1.5 signing key is the same as an OAEP encryption key...

RUSTSEC-2019-0004 Failure to properly verify ed25519 signatures makes any signature valid

Affected versions of this crate did not properly verify ed25519 signatures. Any signature with a correct length was considered valid. This allows an attacker to impersonate any node identity...

Fedora 28 : python-paramiko (2018-8f9d81a3fb)

A flaw was found in the implementation of transport.py in Paramiko, which did not properly check whether authentication was completed before processing other requests. A customized SSH client could simply skip the authentication step. This flaw is a user authentication bypass in the SSH Server...

Docker Notary Forged Signature Vulnerability

Docker Notary is a set of tools for publishing and managing trusted content collections from Docker Inc. in the United States. A security vulnerability exists in the gotuf/signed/verify.go file in Docker Notary versions prior to 0.1. An attacker can exploit this vulnerability to forge signatures ...

CVE-2015-9258

In Docker Notary before 0.1, gotuf/signed/verify.go has a Signature Algorithm Not Matched to Key vulnerability. Because an attacker controls the field specifying the signature algorithm, they might for example be able to forge a signature by forcing a misinterpretation of an RSA-PSS key as Ed2551...

CVE-2015-9258

CVE-2015-9258 concerns Docker Notary prior to 0.1. The vulnerability lies in gotuf/signed/verify.go where the Signature Algorithm Not Matched to Key allows an attacker who controls the signature-algorithm field to forge a signature by forcing RSA-PSS key data to be interpreted as Ed25519 elliptic...

CVE-2015-9258: Undefined Security Weakness

In Docker Notary before 0.1, gotuf/signed/verify.go has a Signature Algorithm Not Matched to Key vulnerability. Because an attacker controls the field specifying the signature algorithm, they might for example be able to forge a signature by forcing a misinterpretation of an RSA-PSS key as Ed2551...
