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-2019-14853
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...
UBUNTU-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...

A timing attack flaw was found in OpenSSL that could allow a malicious user with local access to recover ECDSA P-256 private keys...
GHSA-PWFW-MGFJ-7G3G ecdsa Denial of Service vulnerability in signature verification and signature malleability
possible DoS in signature verification and signature malleability Impact Code using VerifyingKey.verify and VerifyingKey.verifydigest may receive exceptions other than the documented BadSignatureError when signatures are malformed. If those other exceptions are not caught, they may lead to progra...
