Security Bulletin
Summary
GNOME GLib, libcurl and kerberos 5 used by IBM MQ Operator and Queue Manager container images are vulnerable to spoofing attacks, denial of service due to improper memory allocation, and privilege escalation which may lead to bypassing security restrictions. This bulletin identifies the steps required to address these vulnerabilities.
Vulnerability Details
CVEID: CVE-2024-34397
DESCRIPTION: GNOME GLib could allow a remote attacker to conduct spoofing attacks, caused by a flaw when a GDBus-based client subscribes to signals from a trusted system service. By sending specially crafted D-Bus signals, an attacker could exploit this vulnerability perform unicast spoofing attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/290032 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2024-37370
DESCRIPTION: MIT Kerberos 5 (aka krb5) could allow a remote attacker to bypass security restrictions, caused by improper access control. By sending a specially crafted request to modify the plaintext Extra Count field of a confidential GSS krb5 wrap token, an attacker could exploit this vulnerability to cause the unwrapped token to appear truncated to the application.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/296012 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H)
CVEID: CVE-2024-37371
DESCRIPTION: MIT Kerberos 5 (aka krb5) is vulnerable to a denial of service, caused by an invalid memory reads during GSS message token handling. By sending specially crafted message tokens, a remote authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/296013 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2024-2398
DESCRIPTION: cURL libcurl is vulnerable to a denial of service, caused by a memory leak when allowing HTTP/2 server push. By sending a specially crafted PUSH_PROMISE frames with an excessive amount of headers, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/286430 for the current score.

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.
