| <strong>CVE-2021-28129 DEB packaging for Apache OpenOffice 4.1.8 installed with a non-root userid and groupid</strong> |
| </p> |
| <p style="text-align:center; font-size:larger"> |
| <strong>Fixed in Apache OpenOffice 4.1.11</strong> |
| </p> |
| <p> |
| <strong>Description</strong> |
| </p> |
| <p> |
| While working on Apache OpenOffice 4.1.8 a developer discovered that the DEB package did not install |
| using root, but instead used a userid and groupid of 500. This both caused issues with desktop |
| integration and could allow a crafted attack on files owned by that user or group if they exist. |
| </p> |
| <p> |
| <strong>Severity: Moderate</strong> |
| </p> |
| <p> |
| There are no known exploits of this vulnerability. |
| <br /> |
| A proof-of-concept demonstration exists. |
