Stagefright wakes up the mobile eco-system
Not everyday you get to wake up an entire eco-system !
Stagefright discovery by Joshua Drake (@jduck) at Zimperium – Mobile Threat Protection. At the time of writing this blog, ZHA has more than 25 members, comprising top 3 Android smartphone vendors, and 5 out of top 10 mobile carriers (by revenue) globally. Zimperium Handset Alliance (ZHA) members are the first to receive security patches, updates on new vulnerabilities, and other important mobile security related information from other members of ZHA. Vendors and carriers that wishes to join ZHA, apply here.
Please keep in mind that we are vetting applicants in an effort to ensure that sensitive information disseminated via this alliance stays within organizations actually charged with responding to Android security issues.
Update: A twitter user wrote that he has an information leak vulnerability in libstagefright that allows to bypass ASLR – which would make the vulnerability dangerous even on 5.1.1 before the latest Stagefright update.
- Last week, Stagefright patches and POC files were made public by Zimperium.
- Zimperium zLabs released an app to test if your device is vulnerable to Stagefright related CVEs. The Stagefright Detector app can be downloaded for free from the Google Play Store.
- Carriers and Vendors are uniting through ZHA to provide security updates to end-users
