Hi, We have recently discovered a series of vulnerabilities in Firefox for Android that allows a malicious application to successfully derandomize the Firefox profile directory name in a practical amount of time and then leak sensitive data (such as cookies and cached information) which reside in that directory, breaking Android's sandbox: 1. (CVE-2014-1516) Profile Directory Name Weak Randomization. 2. (CVE-2014-1484) Profile Directory Name Leaks to Android System Log. 3. (CVE-2014-1515) Automatic File Download to SD Card. 4. (CVE-2014-1506) Crash Reporter File Manipulation. The full analysis with exploitation techniques can be found in our whitepaper. Important links: 1. Blog post: http://bit.ly/1drYsZp 2.
