## What to check

- Applies to: The 12 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

CERT-FR has published an advisory covering twelve vulnerabilities affecting Apache OpenOffice versions prior to 4.1.17. The flaws collectively allow an attacker to achieve remote code execution, breach data confidentiality and integrity, bypass security policies, and cause denial of service. No specific attack vector details or exploitation techniques are provided in the advisory itself; defenders are referred to the OpenOffice vendor security bulletins for each individual CVE.

There is no indication in this advisory that any of these vulnerabilities are being actively exploited in the wild. The recommended mitigation is straightforward: organizations running OpenOffice should update to version 4.1.17 or later as soon as patches are available, per the vendor's security bulletins referenced in the documentation section.
