CVE-2021-28129 DEB packaging for Apache OpenOffice 4.1.8 installed with a non-root userid and groupid
Fixed in Apache OpenOffice 4.1.11
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.
There are no known exploits of this vulnerability.
A proof-of-concept demonstration exists.
