nss: timing attack against RSA decryption

It was discovered that the numerical library used in NSS for RSA cryptography leaks information whether high order bits of the RSA decryption result are zero. This information can be used to mount a Bleichenbacher or Manger like attack against all RSA decryption operations. As the leak happens...

BIT-GOLANG-2021-34558

The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic...

BIT-NODE-2022-3786 X.509 Email Address Variable Length Buffer Overflow

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate...

BIT-GOLANG-2022-27536

Certificate.Verify in crypto/x509 in Go 1.18.x before 1.18.1 can be caused to panic on macOS when presented with certain malformed certificates. This allows a remote TLS server to cause a TLS client to panic...

Timing Attack

Cryptography is vulnerable to a Timing Attack. This vulnerability is due to the predictable structure of padding in ciphertexts during RSA encryption. This flaw enables an attacker to distinguish between different types of padding errors, potentially leading to the decryption of captured messages...

CVE-2023-50782

A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data...
