Description

This security bulletin contains information about 2 vulnerabilities.


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

CWE-ID: CWE-203 - Observable discrepancy

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-326 - Inadequate Encryption Strength

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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.
