**Name of the Vulnerable Software and Affected Versions** Android versions prior to 4.4.4 Android versions 5.0.x prior to 5.0.2 Android versions 5.1.x prior to 5.1.1 Android versions 6.x before 2016-09-01 Android versions 7.0 before 2016-09-01 **Description** The issue is related to multiple stack-based buffer overflows in the AVCC reassembly implementation in Utils.cpp in libstagefright in MediaMuxer. This allows remote attackers to execute arbitrary code via a crafted media file. **Recommendations** For Android versions prior to 4.4.4, update to version 4.4.4 or later. For Android versions 5.0.x prior to 5.0.2, update to version 5.0.2 or later. For Android versions 5.1.x prior to 5.1.1, update to version 5.1.1 or later. For Android versions 6.x before 2016-09-01, update to a version released after 2016-09-01. For Android versions 7.0 before 2016-09-01, update to a version released after 2016-09-01.

**Name of the Vulnerable Software and Affected Versions** Android versions 4.x through 4.4.3 Android versions 5.0.x through 5.0.1 Android versions 5.1.x through 5.1.0 Android versions 6.x before 2016-06-01 **Description** The issue allows attackers to gain privileges via a crafted application, potentially obtaining Signature or SignatureOrSystem access. This is due to insufficient input validation in the libstagefright component of the Android mediaserver. Exploitation of this issue may enable a remote attacker to elevate their privileges using a specially crafted application. **Recommendations** For Android versions 4.x through 4.4.3, update to version 4.4.4 or later. For Android versions 5.0.x through 5.0.1, update to version 5.0.2 or later. For Android versions 5.1.x through 5.1.0, update to version 5.1.1 or later. For Android versions 6.x before 2016-06-01, ensure your device is updated with the latest security patch released on or after 2016-06-01.
