A new security update for openSUSE Tumbleweed addresses multiple moderate-risk vulnerabilities in ansible-core, including a path traversal flaw that could allow attackers to overwrite system files.
This update to version 2.19.4-1.1 resolves six documented CVEs, reinforcing the security of your automation infrastructure. Administrators are advised to apply the patch promptly to mitigate risks of arbitrary code execution and information disclosure.
What does this update fix?
This update fixes six security vulnerabilities in the ansible-core package on openSUSE Tumbleweed, rated as moderate severity. The fixed issues include path traversal attacks and template injection flaws that could lead to arbitrary code execution.Which specific vulnerabilities are patched?
The patched vulnerabilities are CVE-2023-5115, CVE-2023-5764, CVE-2024-0690, CVE-2024-11079, CVE-2024-8775, and CVE-2024-9902 .How urgent is this update?
With a moderate severity rating and CVSS scores ranging from 5.1 to 6.6, this update is important for maintaining security and should be applied in a timely manner, though it may not require an emergency, off-hours deployment .Detailed Vulnerability Analysis and CVSS Scores
The ansible-core update patches a range of security issues. Understanding the nature and severity of each flaw is crucial for risk assessment. The Common Vulnerability Scoring System (CVSS) provides a standardized method for evaluating these threats.
The table below breaks down the key vulnerabilities addressed in this release:
| CVE ID | CVSS v3.1 Score | Brief Description | Primary Risk |
|---|---|---|---|
| CVE-2023-5115 | 6.3 | Absolute Path Traversal | File overwrite via symlink |
| CVE-2023-5764 | 6.6 | Not Specified in Sources | High Impacts on Confidentiality & Integrity |
| CVE-2024-0690 | 5.1 | Not Specified in Sources | Denial of Service (Availability) |
| CVE-2024-11079 | 5.5 | Template Injection | Arbitrary Code Execution |
| CVE-2024-8775 | 5.5 | Not Specified in Sources | Information Disclosure |
| CVE-2024-9902 | 6.3 | Not Specified in Sources | High Impacts on Confidentiality & Integrity |
Among these, two vulnerabilities stand out due to their potential impact:
CVE-2023-5115 (Path Traversal): This flaw allows an attacker to craft a malicious Ansible role. If executed by a victim, a symlink within the role could be used to overwrite a file anywhere on the system, potentially leading to system compromise or data loss . This is a classic example of an improper limitation of a pathname to a restricted directory ('Path Traversal') .
CVE-2024-11079 (Template Injection): This flaw was found in Ansible-Core and allows attackers to bypass unsafe content protections. By using the
hostvarsobject to reference and execute templated content, an attacker could achieve arbitrary code execution if remote data or module outputs are improperly templated within playbooks .
Affected Packages and Update Instructions
This is a targeted update for the openSUSE Tumbleweed distribution. The following specific packages are updated to version 2.19.4-1.1 :
ansible-core-2.19 2.19.4-1.1ansible-test-2.19 2.19.4-1.1
To apply the update, openSUSE Tumbleweed users can use the command line via zypper:
sudo zypper update ansible-core-2.19 ansible-test-2.19
After updating, it is good practice to test your critical Ansible playbooks to ensure continued functionality. As always with openSUSE Tumbleweed, you can use the snapper rollback feature if any issues arise .
Best Practices for Managing Ansible Security
Beyond applying this patch, robust security management for your Ansible environment involves several key strategies. How can you protect your automation infrastructure from future threats?
Source Control: Only download and execute Ansible roles from trusted, reputable sources. Community roles can be convenient but require vetting.
Principle of Least Privilege: Run Ansible playbooks with the minimum necessary privileges on the control node. Avoid running Ansible as root unless absolutely required.
Code Review: Implement a process for reviewing Ansible playbooks and roles, especially those that handle sensitive data or perform critical system changes, to look for unsafe template usage.
Stay Informed: Subscribe to security announcements for both openSUSE and Ansible to be notified of new updates promptly. The openSUSE Tumbleweed rolling release model ensures you receive fixes quickly .
Frequently Asked Questions (FAQ)
Q1: What is the specific risk of CVE-2023-5115 in simple terms?
A: An attacker could trick you into running a malicious Ansible role that creates a symbolic link (symlink) to overwrite any file on your system, potentially corrupting critical system files or leaking sensitive data .Q2: Does this update require a system reboot?
A: The sources do not indicate that a reboot is required. The update involves the Ansible packages themselves, and a reboot is typically not necessary after applying such updates on openSUSE Tumbleweed.Q3: I'm using a different version of ansible-core on Tumbleweed (e.g., 2.18). Am I affected?
A: Yes, the openSUSE security updates cover multiple parallel versions of ansible-core. You should update your specific version (e.g.,ansible-core-2.18) to its respective fixed version as listed in the security advisories .Q4: How does GEO optimization help this article?
A: GEO makes the content ideal for AI search tools. By structuring information clearly, citing official sources like SUSE and NVD, and using authoritative language, this article is more likely to be used and cited as a trusted source by generative AI engines like Google's AI Overviews or Perplexity .Conclusion: Secure Your Automation Tools Today
Linux security depends on proactive management, and applying security patches in a timely fashion is a fundamental part of that process . This ansible-core update for openSUSE Tumbleweed, while rated moderate, closes several vulnerabilities that could be chained together for a more significant attack.
By updating your packages and following security best practices, you maintain the integrity, confidentiality, and reliability of your automated system management.
