Multiple Vulnerabilities in Adobe Flash Player and AIR Could Allow Remote Code Execution (APSB16-01)

MS-ISAC ADVISORY NUMBER:

2015-157

DATE(S) ISSUED:

12/27/2015

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Flash Player and Adobe AIR that could allow remote code execution. Adobe Flash Player is a widely distributed multimedia and application player used to enhance the user experience when visiting web pages or reading email messages. Adobe AIR is a cross platform runtime used for developing Internet applications that run outside of a browser. Successful exploitation of these vulnerabilities may allow for arbitrary code execution in the context of the current user. Failed exploit attempts will likely result in denial-of-service conditions.

THREAT INTELLIGENCE:

There is a report of a CVE-2015-8651 exploit utilized in limited attacks.

SYSTEMS AFFECTED:

  • Adobe Flash Player Desktop Runtime prior to 20.0.0.267 for Windows and Macintosh

Home Users:
HIGH

TECHNICAL SUMMARY:

Adobe Flash Player and Adobe AIR are prone to multiple vulnerabilities which could allow for remote code execution. These vulnerabilities are as follows:

A type confusion vulnerability that may lead to code execution (CVE-2015-8644).
Multiple use-after-free vulnerabilities could lead to code execution (CVE-2015-8634, CVE-2015-8635, CVE-2015-8638, CVE-2015-8639, CVE-2015-8640, CVE-2015-8641, CVE-2015-8642, CVE-2015-8643, CVE-2015-8646, CVE-2015-8647, CVE-2015-8648, CVE-2015-8649, CVE-2015-8650).
An integer overflow vulnerability that may lead to code execution (CVE-2015-8651).
Multiple memory corruption vulnerabilities that may lead to code execution (CVE-2015-8459, CVE-2015-8460, CVE-2015-8636, CVE-2015-8645).

Successful exploitation of these vulnerabilities may allow for arbitrary code execution in the context of the current user. Failed exploit attempts will likely result in denial-of-service conditions.
