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-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.
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-2019-16732 2 Petwant, Skymee 4 Pf-103, Pf-103 Firmware, Petalk Ai and 1 more 2021-07-21 9.3 HIGH 8.1 HIGH

CVE-2020-15302 1 Argent 1 Recoverymanager 2021-07-21 5.0 MEDIUM 7.5 HIGH
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.
CVE-2019-20597 1 Google 1 Android 2021-07-21 6.4 MEDIUM 9.1 CRITICAL
An issue was discovered on Samsung mobile devices with N(7.1), O(8.x), and P(9.0) software. SPENgesture allows arbitrary applications to read or modify user-input logs. The Samsung ID is SVE-2019-14170 (June 2019).
CVE-2021-23992 1 Mozilla 1 Thunderbird 2021-07-08 4.3 MEDIUM 4.3 MEDIUM
Thunderbird did not check if the user ID associated with an OpenPGP key has a valid self signature. An attacker may create a crafted version of an OpenPGP key, by either replacing the original user ID, or by adding another user ID. If Thunderbird imports and accepts the crafted key, the Thunderbird user may falsely conclude that the false user ID belongs to the correspondent. This vulnerability affects Thunderbird < 78.9.1.
CVE-2021-3196 1 Hitachi 1 Id Bravura Security Fabric 2021-06-24 6.5 MEDIUM 8.8 HIGH
An issue was discovered in Hitachi ID Bravura Security Fabric 11.0.0 through 11.1.3, 12.0.0 through 12.0.2, and 12.1.0. When using federated identity management (authenticating via SAML through a third-party identity provider), an attacker can inject additional data into a signed SAML response being transmitted to the service provider (ID Bravura Security Fabric). The application successfully validates the signed values but uses the unsigned malicious values. An attacker with lower-privilege access to the application can inject the username of a high-privilege user to impersonate that user.
CVE-2021-32685 1 Togatech 1 Tenvoy 2021-06-23 7.5 HIGH 9.8 CRITICAL
tEnvoy contains the PGP, NaCl, and PBKDF2 in node.js and the browser (hashing, random, encryption, decryption, signatures, conversions), used by TogaTech.org. In versions prior to 7.0.3, the `verifyWithMessage` method of `tEnvoyNaClSigningKey` always returns `true` for any signature that has a SHA-512 hash matching the SHA-512 hash of the message even if the signature was invalid. This issue is patched in version 7.0.3. As a workaround: In `tenvoy.js` under the `verifyWithMessage` method definition within the `tEnvoyNaClSigningKey` class, ensure that the return statement call to `this.verify` ends in `.verified`.
CVE-2021-29500 1 Bubble Fireworks Project 1 Bubble Fireworks 2021-06-15 5.0 MEDIUM 7.5 HIGH
bubble fireworks is an open source java package relating to Spring Framework. In bubble fireworks before version 2021.BUILD-SNAPSHOT there is a vulnerability in which the package did not properly verify the signature of JSON Web Tokens. This allows to forgery of valid JWTs.
