CVE-2016-8856

Foxit Reader for Mac 2.1.0.0804 and earlier and Foxit Reader for Linux 2.1.0.0805 and earlier suffered from a vulnerability where weak file permissions could be exploited by attackers to execute arbitrary code. After the installation, Foxit Reader's core files were world-writable by default, allowing an attacker to overwrite them with backdoor code, which when executed by privileged user would result in Privilege Escalation, Code Execution, or both.
