Dan Goodin writing for Ars about newly published vulnerabilities:
There’s a new round of Stagefright vulnerabilities that allows attackers to execute malicious code on more than one billion phones running ancient as well as much more recent versions of Google’s Android operating system.
Stagefright 2.0, as it’s being dubbed by researchers from security firm Zimperium, is a set of two bugs that are triggered when processing specially designed MP3 audio or MP4 video files. The first flaw, which is found in the libutils library and is indexed as CVE-2015-6602, resides in every Android version since 1.0, which was released in 2008. The vulnerability can be exploited even on newer devices with beefed up defenses by exploiting a second vulnerability in libstagefright, a code library Android uses to process media files. Google still hasn’t issued a CVE index number for this second bug.
When combined, the flaws allow attackers to used booby-trapped audio or video files to execute malicious code on phones running Android 5.0 or later. Devices running 5.0 or earlier can be similarly exploited when they use the vulnerable function inside libutils, a condition that depends on what third-party apps are installed and what functionality came preloaded on the phone.
It is always the wrong time to be an Android user.
