opencryptoki: timing side-channel in handling of RSA PKCS#1 v1.5 padded ciphertexts (Marvin)

A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key...

AZL-34206 CVE-2024-0914 affecting package opencryptoki 3.17.0-1

A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key...

UBUNTU-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-2020-20949

Bleichenbacher's attack on PKCS 1 v1.5 padding for RSA in STM32 cryptographic firmware library software expansion for STM32Cube UM1924. The vulnerability can allow one to use Bleichenbacher's oracle attack to decrypt an encrypted ciphertext by making successive queries to the server using the...
