“Adobe has released security updates for Adobe Flash Player for Windows, macOS, Linux and Chrome OS. These updates address important vulnerabilities in Adobe Flash Player 30.0.0.134 and earlier versions. Successful exploitation could lead to arbitrary code execution in the context of the current user.” reads the security advisory published by Adobe.
Adobe fixed two critical arbitrary code execution flaws in Acrobat and Reader (CVE-2018-12808, CVE-2018-12799) for Windows and macOS.

| Untrusted pointer dereference | Arbitrary Code Execution | Critical | CVE-2018-12799 |
Adobe also addressed a DLL hijacking vulnerability in the Creative Cloud Desktop Application installer for Windows can lead to privilege escalation.
The last “moderate” issues addressed by Adobe are two cross-site scripting (XSS) flaws that affect the Experience Manager product that can lead to information disclosure and an input validation bypass issue that can be exploited by an attacker to modify information.
Adobe is not aware of attacks in the wild that have exploited the vulnerabilities, and it doesn’t expect to see attacks exploiting them soon.
