Security Bulletin
Summary
IBM Virtualization Engine TS7700 is susceptible to a denial of service due to the use of OpenSSL (CVE-2024-6119). OpenSSL is used in TS7700 to encrypt data in flight during EKM communications, Secure Data Transfer between clusters, and for TS7700 Advanced Object Store for DS8000.
Vulnerability Details
CVEID: CVE-2024-6119
DESCRIPTION: Issue summary: Applications performing certificate name checks (e.g., TLS
clients checking server certificates) may attempt to read an invalid memory
address resulting in abnormal termination of the application process.
Impact summary: Abnormal termination of an application can a cause a denial of
service.
Applications performing certificate name checks (e.g., TLS clients checking
server certificates) may attempt to read an invalid memory address when
comparing the expected name with an `otherName` subject alternative name of an
X.509 certificate. This may result in an exception that terminates the
application program.
Note that basic certificate chain validation (signatures, dates, ...) is not
affected, the denial of service can occur only when the application also
specifies an expected DNS name, Email address or IP address.
TLS servers rarely solicit client certificates, and even when they do, they
generally don't perform a name check against a reference identifier (expected
identity), but rather extract the presented identity after checking the
certificate chain. So TLS servers are generally not affected and the severity
of the issue is Moderate.
The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.

Note: End of Development (EoD) support was announced for 3957-VEC, effective 31 December 2023, after which time no more code fixes will be provided. Please see https://www.ibm.com/docs/en/announcements/2023-hardware-maintenance-services-withdrawal for more information.
Remediation/Fixes
IBM strongly recommends addressing the vulnerability now by visiting https://tape.ibmrcl.enterpriseappointments.com/v2/ or contacting IBM Service at 1-800-IBM-SERV to arrange an upgrade to the latest microcode version followed by the installation of the appropriate VTD_EXEC as needed. Minimum microcode versions are shown below:
| Machine Type | Model | Release | Fix |
| 3957 | VED | R5.4 | Upgrade to 8.54.2.17 + VTD_EXEC.279 - OR - Upgrade to 8.54.1.27 + VTD_EXEC.279 |
| R6.0 | Upgrade to 8.60.0.115 + VTD_EXEC.279 | ||
| 3948 | VED | R5.4 | Upgrade to 8.54.2.17 + VTD_EXEC.279 - OR - Upgrade to 8.54.1.27 + VTD_EXEC.279 |
| R6.0 | Upgrade to 8.60.0.115 + VTD_EXEC.279 | ||
| 3948 | VEF | R6.0 | Upgrade to 8.60.0.115 + VTD_EXEC.279 |
The minimum VTD_EXEC version is shown below:
| VTD_EXEC Package | Version |
| VTD_EXEC.279 | v1.20 |
Workarounds and Mitigations
Although IBM recommends that you upgrade to the fixes identified above, you can mitigate, but not eliminate the risk of these vulnerabilities by restricting physical and network access to the TS7700 to authorized users and IBM Service Personnel only.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
