Mozilla Firefox 'app_tmp' Directory Insecure Permissions Vulnerability
Mozilla Firefox for Android is prone to an insecure directory permissions vulnerability.
An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions; this may aid in launching further attacks.
Note: This issue was previously discussed in BID 58818 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2013-30 through -40 Multiple Vulnerabilities), but has been moved to its own record to better document it.
This issue is fixed in Firefox 20.0.
