Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-09)

ITS Advisory Number: 
2015-051
Date(s) Issued: 
Tuesday, May 12, 2015
Subject: 
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-09)
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 17.0.0.169 and earlier versions
  • Adobe Flash Player 13.0.0.281 and earlier 13.x versions
  • Adobe Flash Player 11.2.202.457 and earlier 11.x versions
  • AIR Desktop Runtime 17.0.0.144 and earlier versions
  • AIR SDK and SDK & Compiler 17.0.0.144 and earlier versions

Description: 

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

  • Memory corruption vulnerabilities that could lead to code execution (CVE-2015-3078, CVE-2015-3089, CVE-2015-3090, CVE-2015-3093).
  • A heap overflow vulnerability that could lead to code execution (CVE-2015-3088). 
  • A time-of-check time-of-use (TOCTOU) race condition that could be exploited to bypass Protected Mode in Internet Explorer (CVE-2015-3081). 
  • Validation bypass issues that could be exploited to write arbitrary data to the file system under user permissions (CVE-2015-3082, CVE-2015-3083, CVE-2015-3085).  
  • An integer overflow vulnerability that could lead to code execution (CVE-2015-3087). 
  • A type confusion vulnerability that could lead to code execution (CVE-2015-3077, CVE-2015-3084, CVE-2015-3086).
  • A use-after-free vulnerability that could lead to code execution (CVE-2015-3080).
  • Memory leak vulnerabilities that could be used to bypass ASLR (CVE-2015-3091, CVE-2015-3092). 
  • A security bypass vulnerability that could lead to information disclosure (CVE-2015-3079), and provide additional hardening to protect against 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.
