Vulnerability Type: Overflow +Priv 
CWE ID: CWE-119
Summary: mediaserver in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-06-01 does not validate OMX buffer sizes, which allows attackers to gain privileges via a crafted application, as demonstrated by obtaining Signature or SignatureOrSystem access, aka internal bug 27207275.
Commit Message: DO NOT MERGE Verify OMX buffer sizes prior to access

Bug: 27207275
