Type Confusion RCE in Adobe Flash Player bytecode verification
CVE-2017-11292 is a vulnerability in Adobe Flash Player 27.0.0.159 and earlier caused by a flawed bytecode verification procedure. According to the provided content, the verifier allows an untrusted value to be used in the calculation of an array index, which can result in type confusion. The content further notes exploitation involving the vulnerable mediacore.BufferControlParameters class. Successful exploitation can corrupt program state and achieve arbitrary code execution. Public reporting cited in the content shows the flaw was weaponized in malicious Microsoft Word documents embedding Flash content, including DealersChoice.B-based delivery used by APT28, with observed exploitation on Windows 7 and Windows 10 systems running vulnerable Flash and Office 2013 combinations.
