CVE-2017-11292 is an Adobe Flash Player vulnerability affecting version 27.0.0.159 and earlier. The flaw is caused by a defective bytecode verification procedure that permits an untrusted value to be used when calculating an array index, resulting in type confusion. Reporting on in-the-wild exploitation also identified the vulnerable mediacore.BufferControlParameters class as part of the exploit path. Successful exploitation can corrupt memory in a controlled manner and lead to arbitrary code execution in the context of the affected application. The issue affected Flash Player deployments across major desktop operating systems, including Windows, macOS, Linux, and Chrome OS.
