Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-28)

ITS Advisory Number: 
2015-135
Date(s) Issued: 
Tuesday, November 10, 2015
Subject: 
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-28)
Overview: 

Multiple vulnerabilities have been discovered in Adobe Flash Player, a widely distributed multimedia and application player used to enhance the user experience when visiting web pages or reading email messages. Successful exploitation of this vulnerability could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Systems Affected: 
  • Adobe Flash Player Desktop Runtime 19.0.0.245 and earlier Windows and Macintosh
  • Adobe Flash Player Extended Support Release 18.0.0.261 and earlier Windows and Macintosh
  • Adobe Flash Player for Google Chrome 19.0.0.245 and earlier Windows, Macintosh and Linux
  • Adobe Flash Player for Microsoft Edge and Internet Explorer 11 19.0.0.245 and earlier Windows 10
  • Adobe Flash Player for Internet Explorer 10 and 11 19.0.0.245 and earlier Windows 8.0 and 8.1
  • Adobe Flash Player for Linux 11.2.202.548 and earlier Linux
  • AIR Desktop Runtime 19.0.0.241 and earlier Windows and Macintosh
  • AIR SDK 19.0.0.241 and earlier Windows, Macintosh, Android and iOS
  • AIR SDK & Compiler 19.0.0.241 and earlier Windows, Macintosh, Android and iOS

Description: 

Adobe Flash Player is prone to multiple vulnerabilities. These vulnerabilities are as follows:

  • A type confusion vulnerability that could be exploited that could lead to code execution (CVE-2015-7659).
  • A security bypass vulnerability that could be exploited to write arbitrary data to the file system under user permissions (CVE-2015-7662).
  • A use-after-free vulnerabilities that could lead to code execution (CVE-2015-7651, CVE-2015-7652, CVE-2015-7653, CVE-2015-7654, CVE-2015-7655, CVE-2015-7656, CVE-2015-7657, CVE-2015-7658, CVE-2015-7660, CVE-2015-7661, CVE-2015-7663, CVE-2015-8042, CVE-2015-8043, CVE-2015-8044, CVE-2015-8046).

Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Actions: 
  • Install the updates provided by Adobe immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments, especially those from un-trusted sources.
