Overview

Affected versions of this package are vulnerable to Observable Timing Discrepancy due to improper handling of RSA decryption operations. An attacker can decrypt ciphertexts or forge signatures by exploiting the side-channel leakage in the RSA decryption process (Marvin).

Note:

This is only exploitable if the attacker has network access and the ability to observe the decryption of ciphertexts.
