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...

Information Disclosure

libcryptopp.so is vulnerable to Information Disclosure. The vulnerability exists due to side channel leakage Marvin Attack which allows an attacker to to infer sensitive information during PKCS1 v1.5 decryption...

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...

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...

Updated cjose packages fix a security vulnerability

The updated packages fix a security vulnerability: The AES GCM decryption routine incorrectly uses the Tag length from the actual Authentication Tag provided in the JWE. The spec says that a fixed length of 16 octets must be applied. Therefore this bug allows an attacker to provide a truncated...
