|Stagefright 2.0 Exploit What You Need To Know And How To Prevent It(android Bug) by Smartixy(m): 5:20pm On Oct 03, 2015|
Stagefright Exploit is remotely exploitable software bug that affects versions 2.2 (“Froyo”) and newer of the Android operating system. It allows an attacker to perform arbitrary operations on the victim device through remote code execution and privilege escalation.
A new Stagefright threat that targets Android phones through MP3 and MP4 files has been discovered. The code hides within the audio file and activates once users preview it or visit a page where the file is embedded. This audio preview function exists within most versions of Android, so nearly every Android device is susceptible to this exploit. The malicious code can also be sent to a user’s phone via public Wi-Fi.
The bug has been provided with multiple CVE identifiers, CVE-2015-1538, CVE-2015-1539, CVE-2015-3824, CVE-2015-3826, CVE-2015-3827, CVE-2015-3828, CVE-2015-3829 and (the later found) CVE-2015-3864, which are collectively referred to as the Stagefright bug
