Stagefright 2.0 Exploits Android Vulnerabilities

Newly found vulnerabilities in the way Android handles media files can allow attackers to compromise devices by tricking users into visiting maliciously crafted Web pages.

The vulnerabilities can lead to remote code execution on almost all devices that run Android, starting with version 1.0 of the OS released in 2008 to the latest 5.1.1, researchers from mobile security firm Zimperium said in a report published Thursday.

The flaws are in the way Android processes the metadata of MP3 audio files and MP4 video files, and they can be exploited when the Android system or another app that relies on Android’s media libraries previews such files.

The Zimperium researchers found similar multimedia processing flaws earlier this year in an Android library called Stagefright that could have been exploited by simply sending Android devices a maliciously crafted MMS message.

Those flaws triggered a coordinated patching effort from device manufacturers that Android’s lead security engineer, Adrian Ludwig, called the “single largest unified software update in the world.” It also contributed to Google, Samsung and LG committing to monthly security updates going forward.

One of the flaws newly discovered by Zimperium is located in a core Android library called libutils and affects almost all devices running Android versions older than 5.0 (Lollipop). The vulnerability can also be exploited in Android Lollipop (5.0 – 5.1.1) by combining it with another bug found in the Stagefright library.

The Zimperium researchers refer to the new attack as Stagefright 2.0 and believe that it affects more than 1 billion devices.

Since the previous attack vector of MMS was closed in newer versions of Google Hangouts and other messaging apps after the previous Stagefright flaws were found, the most straight-forward exploitation method for the latest vulnerabilities is through Web browsers, the Zimperium researchers said.

Zimperium reported the flaws to Google on Aug. 15 and plans to release proof-of-concept exploit code once a fix is released.

That fix will come on Oct. 5 as part of the new scheduled monthly Android security update, a Google representative said.

Mobile Security Threats Continue To Grow

According to industry analysts, mobile device shipments will exceed a billion devices in 2015 and will rapidly outrun PC shipments. That’s great news for end user convenience, mobility, and work-anywhere productivity. But it also means that enterprises must prepare for the fact that the criminals will target these devices with attack exploits, spyware,
and rogue applications.

And while IBM’s IT security research team, X-Force, predicts a modest 33 software exploits targeting mobile devices in the year ahead, that’s roughly twice the number of such attack code released in the past year.

The group also sees a number of other troubling mobile security trends. First, when software flaws do surface, many mobile phone makers do not rapidly deploy software patches to devices; malicious apps are often distributed through third-party app markets. Another troubling trend is that some mobile malware can collect end user’s personal information for use in phishing attacks.

An example of vulnerabilities that would make such attacks possible are the two recent Android security flaws that were reported to affect popular handsets including the AT&T Samsung Galaxy SII and various HTC devices.

The security find announced by security researcher Trevor Eckhart, called HTClogger (logging tools introduced by handset maker HTC) that could leak email account information, user location, phone numbers, and messaging logs.

Handset maker HTC said, in a statement, that it is working to quickly issue an update to its customers. “HTC is working very diligently to quickly release a security update that will resolve the issue on affected devices. Following a short testing period by our carrier partners, the patch will be sent over-the-air to customers, who will be notified to download and install it. We urge all users to install the update promptly,” the company said.
