CVE-2020-15093 1 Amazon 1 Tough 2021-10-26 5.0 MEDIUM 8.6 HIGH
The tough library (Rust/crates.io) prior to version 0.7.1 does not properly verify the threshold of cryptographic signatures. It allows an attacker to duplicate a valid signature in order to circumvent TUF requiring a minimum threshold of unique signatures before the metadata is considered valid. A fix is available in version 0.7.1. CVE-2020-6174 is assigned to the same vulnerability in the TUF reference implementation.

Acrobat Reader DC for macOS versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a security feature bypass. While the practical security impact is minimal, a defense-in-depth fix has been implemented to further harden the Adobe Reader update process.
CVE-2020-24429 3 Adobe, Apple, Microsoft 6 Acrobat, Acrobat Dc, Acrobat Reader and 3 more 2021-09-08 6.8 MEDIUM 7.8 HIGH
Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) for macOS are affected by a signature verification bypass that could result in local privilege escalation. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2020-26540 2 Apple, Foxitsoftware 3 Macos, Foxit Reader, Phantompdf 2021-09-08 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Foxit Reader and PhantomPDF before 4.1 on macOS. Because the Hardened Runtime protection mechanism is not applied to code signing, code injection (or an information leak) can occur.
CVE-2021-34433 1 Eclipse 1 Californium 2021-08-26 5.0 MEDIUM 7.5 HIGH
In Eclipse Californium version 2.0.0 to 2.6.4 and 3.0.0-M1 to 3.0.0-M3, the certificate based (x509 and RPK) DTLS handshakes accidentally succeeds without verifying the server side's signature on the client side, if that signature is not included in the server's ServerKeyExchange.
CVE-2021-38195 1 Parity 1 Libsecp256k1 2021-08-16 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the libsecp256k1 crate before 0.5.0 for Rust. It can verify an invalid signature because it allows the R or S parameter to be larger than the curve order, aka an overflow.
CVE-2019-14859 2 Python-ecdsa Project, Redhat 4 Python-ecdsa, Ceph Storage, Openstack and 1 more 2021-08-04 6.4 MEDIUM 9.1 CRITICAL
A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.
CVE-2021-22708 1 Schneider-electric 12 Evlink City Evc1s22p4, Evlink City Evc1s22p4 Firmware, Evlink City Evc1s7p4 and 9 more 2021-07-28 6.5 MEDIUM 7.2 HIGH

CVE-2020-1026 1 Microsoft 1 Research Javascript Cryptography Library 2021-07-21 7.5 HIGH 9.8 CRITICAL
A Security Feature Bypass vulnerability exists in the MSR JavaScript Cryptography Library that is caused by multiple bugs in the library’s Elliptic Curve Cryptography (ECC) implementation.An attacker could potentially abuse these bugs to learn information about a server’s private ECC key (a key leakage attack) or craft an invalid ECDSA signature that nevertheless passes as valid.The security update addresses the vulnerability by fixing the bugs disclosed in the ECC implementation, aka 'MSR JavaScript Cryptography Library Security Feature Bypass Vulnerability'.
CVE-2020-13593 1 Ti 1 Simplelink-cc2640r2 Software Development Kit 2021-07-21 5.8 MEDIUM 8.8 HIGH
The Bluetooth Low Energy Secure Manager Protocol (SMP) implementation in Texas Instruments SimpleLink SIMPLELINK-CC2640R2-SDK through 2.2.3 allows the Diffie-Hellman check during the Secure Connection pairing to be skipped if the Link Layer encryption setup is performed earlier. An attacker in radio range can achieve arbitrary read/write access to protected GATT service data, cause a denial of service, or possibly control a device's function by establishing an encrypted session with an unauthenticated Long Term Key (LTK).
CVE-2019-19962 1 Wolfssl 1 Wolfssl 2021-07-21 5.0 MEDIUM 7.5 HIGH
wolfSSL before 4.3.0 mishandles calls to wc_SignatureGenerateHash, leading to fault injection in RSA cryptography.

CVE-2020-28086 1 Zx2c4 1 Password-store 2021-07-21 5.0 MEDIUM 7.5 HIGH
pass through 1.7.3 has a possibility of using a password for an unintended resource. For exploitation to occur, the user must do a git pull, decrypt a password, and log into a remote service with the password. If an attacker controls the central Git server or one of the other members' machines, and also controls one of the services already in the password store, they can rename one of the password files in the Git repository to something else: pass doesn't correctly verify that the content of a file matches the filename, so a user might be tricked into decrypting the wrong password and sending that to a service that the attacker controls. NOTE: for environments in which this threat model is of concern, signing commits can be a solution.
