CentOS 8 : nss (CESA-2024:0105)
The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CESA-2024:0105 advisory. - 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...
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...
Ubuntu 22.04 LTS : Node.js vulnerabilities (USN-6564-1)
The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6564-1 advisory. Hubert Kario discovered that Node.js incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted...

SUSE-SU-2023:4952-1 Security update for gnutls
This update for gnutls fixes the following issues: - CVE-2023-0361: Fixed a Bleichenbacher oracle in the TLS RSA key exchange bsc1208143. - CVE-2023-5981: Fixed timing side-channel inside RSA-PSK key exchange bsc1217277...
php: potential exposure to Marvin attack via unsafe implementation of RSA decryption API
The RSA decryption implementation using PKCS1 v1.5 padding in OpenSSL is vulnerable to a timing side-channel attack known as the Marvin Attack. This vulnerability arises because the execution time of the opensslprivatedecrypt function in PHP with OpenSSL varies based on whether a valid message is...
Siemens SIMATIC and SCALANCE Products Encryption Strength (CVE-2023-0286)
There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1STRING but the public structure definition for GENERALNAME incorrectly specified the type of the x400Address field as ASN1TYPE. This field is subsequentl...
Siemens SIMATIC and SCALANCE Products Encryption Strength (CVE-2022-4304)
A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages fo...
CVE-2023-4421
The NSS code used for checking PKCS1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected...

CVE-2023-4421
CVE-2023-4421 concerns the NSS library’s handling of PKCS#1 v1.5 padding, where timing side-channel leakage exposed information about padding validity and message length. This could enable Bleichenbacher-like attacks, allowing an attacker to decrypt previously intercepted PKCS#1 v1.5 ciphertext (...

Internet Bug Bounty: OpenSSL vulnerable to the Marvin Attack (CVE-2022-4304)
A timing side channel vulnerability in OpenSSL RSA decryption was discovered that could allow plaintext recovery. By measuring decryption time, an attacker could recover RSA plaintext from captured ciphertexts after a large number of decryption attempts. All RSA padding modes were affected. The...
SUSE CVE-2023-6258
A security vulnerability has been identified in the pkcs11-provider, which is associated with Public-Key Cryptography Standards PKCS11. If exploited successfully, this vulnerability could result in a Bleichenbacher-like security flaw, potentially enabling a side-channel attack on PKCS1 1.5...
