Date(s) Issued: 
Tuesday, June 9, 2015
Subject: 
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-11)
Overview: 

Multiple vulnerabilities have been discovered in Adobe Flash Player. 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.

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

Systems Affected: 
  • Adobe Flash Player Desktop Runtime 17.0.0.188 and earlier
  • Adobe Flash Player Extended Support Release 13.0.0.289 and earlier
  • Adobe Flash Player for Google Chrome  17.0.0.188 and earlier
  • Adobe Flash Player for Internet Explorer 10 and Internet Explorer 11 17.0.0.188 and earlier
  • Adobe Flash Player 11.2.202.460 and earlier
  • AIR Desktop Runtime 17.0.0.172 and earlier

Description: 

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

  • Vulnerability (CVE-2015-3096) that could be exploited to bypass the fix for CVE-2014-5333. 
  • Improve memory address randomization of the Flash heap for the Window 7 64-bit platform (CVE-2015-3097). 
  • Vulnerabilities that could be exploited to bypass the same-origin-policy and lead to information disclosure (CVE-2015-3098, CVE-2015-3099, CVE-2015-3102).
  • Stack overflow vulnerability that could lead to code execution (CVE-2015-3100).
  • Permission issue in the Flash broker for Internet Explorer that could be exploited to perform privilege escalation from low to medium integrity level (CVE-2015-3101).    
  • Integer overflow vulnerability that could lead to code execution (CVE-2015-3104).
  • Memory corruption vulnerability that could lead to code execution (CVE-2015-3105).
  • Use-after-free vulnerabilities that could lead to code execution (CVE-2015-3103, CVE-2015-3106, CVE-2015-3107).
  • Memory leak vulnerability that could be used to bypass ASLR (CVE-2015-3108). 

Successful exploitation of these vulnerabilities could result in the attacker gaining the same rights as the logged on user. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Actions: 
  • Install the updates provided by Adobe immediately after appropriate testing
  • Do not open email attachments from unknown or untrusted sources or suspicious emails from trusted sources.
  • Remind users not to visit websites or follow links provided by unknown or untrusted sources.
  • Limit user account privileges to those required only.
