1. stagefright IntroductionThe android froyo version number multimedia engine has changed. Is it new? By default, Android chooses stagefright and does not abandon opencore completely. It mainly creates an OMX layer, but references the OMX-component part of opencore. Stagefright is added at the mediaplayerservice layer, and is in parallel with opencore.

Discussion on Stagefright Vulnerability0x00 Last night, Stagefright reported a major vulnerability, which could cause remote code execution or even sending MMS messages, which may intrude into users' mobile devices. This sounds like a big loophole. As a security personnel, you must take a look at the inside story.0x01 According to the news, for some reasons, the discoverer of the vulnerability has not publi

Metaphor-A real life Stagefright exploit analysis0x00 Summary This article describes how to use Stagefright, one of the most notorious vulnerabilities in Android. Before that, we thought this vulnerability was very difficult to exploit. In this study, we have made a lot of reference to Google's article-exploit-38226 and the research report Google Project Zero: Stagefrightened. This article presents our res

A Preliminary Study on the high-risk vulnerability of Android Stagefright Collation The Stagefright vulnerability can cause remote code execution, or even sending MMS messages, which may intrude into users' mobile devices. This sounds like a big loophole. As a security personnel, you must take a look at the inside story. Heavy lifting According to the news, for some reasons, the discoverer of the vulnerabil

Code exposure using the Android Stagefright Vulnerability When Google and its partners are busy pushing patches to devices of end users, attackers can control the attack code of Android devices without their knowledge. The high-risk vulnerability named Stagefright is located in the Android Media Processing code library. Attackers can exploit this vulnerability to send specially crafted MMS text messages an

Android source code Version: 4.2.2; hardware platform A31 Frontier: In the previous blog, we mentioned the control flow related to stagefright, analyzed the creation of MediaExtractor, AwesomePlayer, StagefrightPlayer, and OMXCodec In the android architecture, and the creation of OMXNodinstance at the underlying layer. This article analyzes the architecture of the underlying plug-in library and decoder component of OMX and how to create our own OMX P

Opencore's approach is to set up a main clock, and audio and video are used as a means of output. In the Stagefright, audio output is through the callback function to move, video is rooted in the audio timestamp to do synchronization. The

115 patches are required to fix the Android Stagefright Bug On June 23, last July, security researchers disclosed the Android Bug known as Stagefright. The vulnerability exists in the code library that processes media formats. It allows attackers to control the target mobile phone using special MMS messages, the master operation is not required throughout the process. Security researchers initially estim

Explore the Stagefright vulnerability: POC and EXP PrefaceIn the previous "Discussion on Stagefright vulnerabilities", we have determined the location where the vulnerabilities are generated, and the entire article stops. After all, this vulnerability has a deep impact, and I do not know the details. This article provides a simple solution for exploiting vulnerabilities. Let's just talk about the idea. The

RTSP support was added into stagefright on gingerbread release: A preliminary foundation module, provides a generic way to asynchronously handle commands and events/messages sequentially in the Schedule thread. each message has a target ID, indicating its corresponding handler, which is then registered in a looper. A looper spawns a thread, and schedules registered handlers to process any messages posted to it. Artspcontroller acts as mediaextracto

From android2.0. Google introduced stagefright and used stagefright in android2.3 to shareLibrary format (libstagefright. So), where awesomeplayer can be used to play video/audio. Awesomeplayer provides many APIs that allow upper-layer applications to use Java/JNI for calling. Here I will briefly describe the video playback process (using the android2.2 source code ). In Java, to play a video, we usually w

In Android 3. X, the processing of HTTP live streaming is independently developed into a nuplayer, independent of the stagefright framework. We have optimized the features of HTTP live. HTTP live streaming is a trend in the future development of streaming media. The HTTP live video experience in Android 2. x is far inferior to that of iPad. I do not know whether or not to separate this part in 3.x has been improved. Currently, the android 3.x pad has
