LG promised to fix Stagefright and release monthly security updates in august 2015. Did they release update for international devices or you guys are still waiting?
About two weeks ago, I tried Zimperium (security firm which discovered Stagefright) stagefright detector and it reported that all is fixed. I have H815 V10d-EUR-XX.
But since then new vulnerabilities in mp3/mp4 parsing has been discovered, also by Zimperium, it was labeled as stagefright 2.0 by some media although it is unrelated to libstagefright. It is similar in nature that media files are used for exploit. https://blog.zimperium.com/zimperiu...me-new-vulnerability-processing-mp3mp4-media/
I tried the detector app just now and it reports the new one CVE-2015-6602 is not fixed.
