Adobe Flash Player Type Confusion Vulnerability. Actively exploited: CISA added this vulnerability to its Known Exploited Vulnerabilities catalog on 03/03/2022. Patch affected systems as an emergency.
| Package | Affected versions | Patched versions |
|---|---|---|
| flash player | ≤ 27.0.0.130≤ 27.0.0.159 | |
| flash player desktop runtime | ≤ 27.0.0.159 |
Adobe Flash Player version 27.0.0.159 and earlier has a flawed bytecode verification procedure, which allows for an untrusted value to be used in the calculation of an array index. This can lead to type confusion, and successful exploitation could lead to arbitrary code execution.
