-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 CVE-2016-6804 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=2016-6804> Apache OpenOffice Advisory <https://www.openoffice.org/security/cves/CVE-2016-6804.html> Title: Windows Installer Execution of Arbitrary Code with Elevated Privileges Version 1.0 Announced October 11, 2016 Description The Apache OpenOffice installer for Windows contained a defective operation that allows execution of arbitrary code with elevated privileges. The location in which the installer is run may have been previously poisoned by a file that impersonates a dynamic-link library that the installer depends upon. The counterfeit is operated instead because of a search-path defect in the installer. The counterfeit will be operated under the administrative privileges of the OpenOffice installer, compromising the user's PC. Severity: Medium There are no known exploits of this vulnerability. Proof-of-concept demonstrations exist. Vendor: The Apache Software Foundation Versions Affected: All Apache OpenOffice versions 4.1.2 and older are affected. OpenOffice.org versions are also affected. Mitigation: Install Apache OpenOffice 4.1.3 for the latest maintenance and cumulative security fixes. Use <https://www.openoffice.org/download/>. Defenses and Work-Arounds: If you are unable to update to 4.1.3, there are other precautions that can be taken. These precautions are also recommended as protection against other software that may have the vulnerability. When executing .exe installers, ensure that the installer is in a file folder that has no files but the installer .exe file. If an installer proposes a folder to extract the setup files into before the actual install, choose the name of a folder that is not in use. Delete such a folder of setup files after the installation completes successfully. To reinstall without downloading again, preserve the installer .exe on private removable storage. Further Information: For additional information and assistance, consult the Apache OpenOffice Community Forums, <https://forum.openoffice.org/> or make requests to the <mailto:users@openoffice.apache.org> public mailing list. Defects not involving suspected security vulnerabilities can be reported via <http://www.openoffice.org/qa/issue_handling/pre_submission.html>.
