Detailsinfo

A vulnerability classified as very critical has been found in Google Android up to 5.1.0 (Smartphone Operating System). This affects an unknown part of the file MPEG4Extractor.cpp of the component libstagefright. The manipulation of the argument NAL as part of a MP4 File leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple buffer overflows in MPEG4Extractor.cpp in libstagefright in Android before 5.1.1 LMY48I allow remote attackers to execute arbitrary code via invalid size values of NAL units in MP4 data, aka internal bug 19641538.

The weakness was published 10/01/2015 as 19641538 (Website). The advisory is shared at groups.google.com. This vulnerability is uniquely identified as CVE-2015-3832 since 05/12/2015.
