This security bulletin contains information about 2 secuirty vulnerabilities.


1) Observable discrepancy (CVE-ID: CVE-2023-33850)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to timing-based side channel in the RSA Decryption implementation. A remote attacker can send an overly large number of trial messages for decryption and gain unauthorized access to sensitive information on the system.


2) Inadequate Encryption Strength (CVE-ID: CVE-2023-32342)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to IBM GSKit is using weak cryptographic algorithms. A remote attacker can send an overly large number of trial messages for decryption and perform a timing-based side channel attack against the RSA Decryption implementation.
