USN-6727-2: NSS regression

USN-6727-1 fixed vulnerabilities in NSS. The update introduced a regression when trying to load security modules on Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that NSS incorrectly handled...

Observable Discrepancy

Overview BouncyCastle is a C implementation of cryptographic algorithms. Affected versions of this package are vulnerable to Observable Discrepancy due to the timing difference between exceptions thrown when processing RSA key exchange handshakes, AKA Marvin. Note: The implemented fix mitigates t...

Sensitive Information Disclosure

GnuTLS is vulnerable to Sensitive Information Disclosure. The vulnerability is due to exploiting deterministic behavior in systems like GnuTLS, particularly when using the GNUTLSPRIVKEYFLAGREPRODUCIBLE flag, which can lead to a noticeable step in nonce size from 513 to 512 bits, exposing a...

The vulnerability of the PrivateDecrypt() function in the cryptographic library of the Node.js software platform, which allows a attacker to execute the Bleichenbacher attack or the Marvin attack.

The vulnerability of the PrivateDecrypt function in the Node.js software library is related to the use of hidden auxiliary channels due to a discrepancy in the timing of decrypting valid and invalid encrypted texts based on the PKCS1 v1.5 cryptographic standard. Exploiting this vulnerability allo...

Ubuntu 20.04 LTS / 22.04 LTS / 23.10 : NSS vulnerabilities (USN-6727-1)

nodejs: vulnerable to timing variant of the Bleichenbacher attack against PKCS#1 v1.5 padding (Marvin)

A flaw was found in Node.js. The privateDecrypt API of the crypto library may allow a covert timing side-channel during PKCS1 v1.5 padding error handling. This issue revealed significant timing differences in decryption for valid and invalid ciphertexts, which may allow a remote attacker to decry...
