- 漏洞描述

Unix system files and directories with invalid permissions can cause several problems. First, the owner must be correct on the system files and directories. If it is not a malicious user could modify the file logged in as a different user. Also, if the owner of the file is invalid it may not allow proper access to the file from the system potentially causing a DoS. Second, system files and directories should not be world writeable. A world writable system directory would allow an attacker rights to place a malicious file in the system directories. Also, if the permissions are set to not allow the system proper access to the file it may result in a DoS for the system or service.
