Summary
A code execution issue in the Java integration in Apache OpenOffice v4.1.16 and earlier allows a crafted untrusted document to trigger executing arbitrary (even remote) code when opened by the user. The issue is expected to be fixed in version 4.1.17, which is in the release candidate phase.
Risk Assessment
Opening a malicious document in Apache OpenOffice can lead to arbitrary code execution, including remote code, on the user's workstation. This may result in full system compromise by an attacker.
Recommendation
Disable Java runtime integration in the Preferences dialog, which prevents the attack, and avoid opening untrusted files. Once version 4.1.17 is released, upgrade Apache OpenOffice to that version.
Other vulnerabilities in Apache OpenOffice
See all- CVE-2014-3524High
Apache OpenOffice before 4.1.1 allows remote attackers to execute arbitrary commands and possibly have other unspecified impact via a crafted Calc spreadsheet.
- CVE-2025-64407Medium
A missing authorization vulnerability in Apache OpenOffice allows an attacker to craft a document that causes external links to be loaded without prompting the user. Such links could also be used to transmit system information, such as environment variables or configuration settings.
- CVE-2025-64406Medium
An out-of-bounds write vulnerability in Apache OpenOffice through 4.1.15 could allow an attacker to craft a document that crashes the program or corrupts other memory areas.
- CVE-2025-64405High
A missing authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In affected versions through 4.1.15, Calc spreadsheets containing DDE links to external files would load their contents without user permission.
- CVE-2025-64404High
A missing authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In affected versions through 4.1.15, documents using background fill images or bullet images linked to external files would load their contents without user permission.
- CVE-2025-64403High
A missing authorization vulnerability in Apache OpenOffice Calc allowed an attacker to craft a document that would cause external data source links to be loaded without prompt. This issue affects versions through 4.1.15.
- CVE-2025-64402Medium
Apache OpenOffice contains a missing authorization vulnerability that allows an attacker to craft a document causing external links to be loaded without prompting the user. Documents with OLE objects linked to external files would load their contents without user permission.
- CVE-2025-64401High
A missing authorization vulnerability in Apache OpenOffice allowed an attacker to craft a document that would cause external links to be loaded without prompting the user. In affected versions, documents using 'floating frames' linked to external files loaded their contents without user permission. The issue is fixed in version 4.1.16.
Original NVD description (English source)
A code execution issue in the Java integration in Apache OpenOffice v4.1.16 and earlier allows a crafted untrusted document to trigger executing arbitrary (even remote) code when opened by the user. This issue is expected to be fixed in version 4.1.17, which is in the release candidate phase. Until then, users can mitigate this issue by disabling Java runtime integration in the Preferences dialog. This prevents the attack. If this is not possible, or as an extra precaution, you can avoid opening open untrusted files entirely. Once 4.1.17 is released, upgrade to that version to fix the issue.
