Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-06)

ITS Advisory Number: 
2015-042
Date(s) Issued: 
Tuesday, April 14, 2015
Subject: 
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-06)
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 17.0.0.134 and earlier versions
  • Adobe Flash Player 13.0.0.277 and earlier 13.x versions
  • Adobe Flash Player 11.2.202.451 and earlier 11.x versions

Description: 

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

  • Multiple memory corruption vulnerabilities that could lead to remote code execution (CVE-2015-0347, CVE-2015-0350, CVE-2015-0352, CVE-2015-0353, CVE-2015-0354, CVE-2015-0355, CVE-2015-0360, CVE-2015-3038, CVE-2015-3041, CVE-2015-3042, CVE-2015-3043).
  • Type confusion vulnerability that could lead to remote code execution (CVE-2015-0356).
  • Buffer overflow vulnerability that could lead to remote code execution (CVE-2015-0348).
  • Use-after-free vulnerabilities that could lead to remote code execution (CVE-2015-0349, CVE-2015-0351, CVE-2015-0358, CVE-2015-3039).
  • Double-free vulnerabilities that could lead to remote code execution (CVE-2015-0346, CVE-2015-0359).
  • Memory leak vulnerabilities that could be used to bypass Address Space Layout Randomization (ASLR) (CVE-2015-0357, CVE-2015-3040).
  • Security bypass vulnerability that could lead to information disclosure (CVE-2015-3044).

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: 

We recommend the following actions be taken:

  • 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.
  • Adobe Flash Player installed with Google Chrome, as well as Internet Explorer on Windows 8.x, will automatically update to version 17.0.0.169 when available.
