Описание
A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS#1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key.
Отчет
This vulnerability in opencryptoki, enabling RSA ciphertext decryption or signing without the private key, is moderate due to the significant effort needed to exploit it, including sending a large number of meticulously crafted messages to a vulnerable API-utilizing service and a precise timing control.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
