[SECURITY] Fedora 31 Update: python-ecdsa-0.13.3-1.fc31

This is an easy-to-use implementation of ECDSA cryptography Elliptic Curve Digital Signature Algorithm, implemented purely in Python, released under the MIT license. With this library, you can quickly create keypairs signing key and verifying key, sign messages, and verify the signatures. The key...

Mbed TLS -- Side channel attack on ECDSA

Janos Follath reports: Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it as it is smaller than RSA keys and not guaranteed to have only large prime factors, and then, by brute force, recover the key...

CVE-2019-15703

An Insufficient Entropy in PRNG vulnerability in Fortinet FortiOS 6.2.1, 6.2.0, 6.0.8 and below for device not enable hardware TRNG token and models not support builtin TRNG seed allows attacker to theoretically recover the long term ECDSA secret in a TLS client with a RSA handshake and mutual...

CVE-2019-15703

Fortinet FortiOS is affected by CVE-2019-15703 where insufficient entropy in the PRNG (DRBG) can theoretically allow recovery of a long-term ECDSA secret in a TLS client with RSA handshake and mutual ECDSA authentication, via flush+reload side-channel attacks in FortiGate VM models only. The vuln...

NewStart CGSL CORE 5.04 / MAIN 5.04 : nss Multiple Vulnerabilities (NS-SA-2019-0193)

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has nss packages installed that are affected by multiple vulnerabilities: - Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of...

Denial Of Service (DoS)

python-ecdsa is vulnerable to denial of service. The package raises unexpected exceptions when a DER signature is malformed, allowing a remote attacker to crash the application by submitting malicious DER signature...

CVE-2019-14859

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...

CVE-2019-14853

An error-handling flaw was found in python-ecdsa before version 0.13.3. During signature decoding, malformed DER signatures could raise unexpected exceptions or no exceptions at all, which could lead to a denial of service...
