Recommendation: Plan a near-term fix — a public PoC already exists.

Integer underflow in the MPEG4Extractor::parseChunk function in MPEG4Extractor.cpp in libstagefright in mediaserver in Android before 5.1.1 LMY48M allows remote attackers to execute arbitrary code via crafted MPEG-4 data, aka internal bug 23034759. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-3824.
