Security Bulletin


Summary

Multiple vulnerabilities in Open Container Initiative runc used by IBM InfoSphere Information Server were addressed.

Vulnerability Details

CVEID:   CVE-2024-21626
DESCRIPTION:   Open Container Initiative runc could allow a remote attacker to bypass security restrictions, caused by an internal file descriptor leak. By persuading a victim to use a specially crafted image, an attacker could exploit this vulnerability to perform container escape to access to the host filesystem.
CVSS Base score: 8.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/281085 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H)

CVEID:   CVE-2023-27561
DESCRIPTION:   Open Container Initiative runc could allow a local authenticated attacker to gain elevated privileges on the system, caused by improper access control in libcontainer/rootfs_linux.go. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges to run custom images.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/249173 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:   CVE-2023-28642
DESCRIPTION:   runc could allow a remote attacker to bypass security restrictions, caused by a symbolic link following vulnerability. By creating a symbolic link inside a container to the /proc directory, an attacker could exploit this vulnerability to bypass AppArmor and SELinux protections.
CVSS Base score: 6.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/251539 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L)

Workarounds and Mitigations

The runc binary can be updated on the microservices tier nodes by just replacing the binary file:

  1. Download a fixed runc binary from the official releases page:
            For example, wget https://github.com/opencontainers/runc/releases/download/v1.1.12/runc.amd64 -O /tmp/runc
  2. Replace the runc binary on the system:
            sudo mv /tmp/runc /usr/local/sbin/runc
  3. Ensure that the runc binary has execute permissions:
            sudo chmod a+x /usr/local/sbin/runc
  4. Confirm that the runc version has changed, by examining the output of the command:
            runc --version

After replacing the runc binary, perform the standard microservices tier node restart procedure:

  1. Use stop_node.sh script to stop microservices tier services.
  2. Reboot the node.
  3. Use start_node.sh script to start microservices tier services.

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.
