Adobe Flash Player type confusion in bytecode verification
CVE-2017-11292 is a type confusion vulnerability in Adobe Flash Player 27.0.0.159 and earlier. According to the provided content, the issue is caused by a flawed bytecode verification procedure that permits an untrusted value to be used in the calculation of an array index. This unsafe index handling can corrupt type assumptions during ActionScript/Flash bytecode processing, resulting in type confusion. Successful exploitation can allow an attacker to execute arbitrary code in the context of the affected Flash Player process. The supporting content also indicates the vulnerability was actively targeted by APT28 via exploit delivery before patches were broadly deployed.
