Security updates available for Adobe Flash Player (APSB14-21)

ITS Advisory Number: 
2014-077
Date(s) Issued: 
Tuesday, September 9, 2014
Subject: 
Security updates available for Adobe Flash Player (APSB14-21)
Overview: 

Multiple vulnerabilities have been discovered in Adobe Flash Player 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.

Successful exploitation 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 access.

Systems Affected: 
  • Adobe Flash Player 14.0.0.179 and earlier versions for Windows and Macintosh
  • Adobe Flash Player 11.2.202.400 and earlier versions for Linux
  • Adobe AIR 14.0.0.178 and earlier
  • Adobe AIR 14.0.0.179 and earlier versions for Android

Description: 

Adobe Flash Player is prone to multiple vulnerabilities that could allow for remote code execution. These vulnerabilities are as follows:

  • Memory leakage vulnerabilities that could be used to bypass memory address randomization (CVE-2014-0557).
  • A security bypass vulnerability (CVE-2014-0554).
  • A use-after-free vulnerability that could lead to code execution (CVE-2014-0553).
  • Memory corruption vulnerabilities that could lead to code execution (CVE-2014-0547, CVE-2014-0549, CVE-2014-0550, CVE-2014-0551, CVE-2014-0552, CVE-2014-0555).
  • A vulnerability that could be used to bypass the same origin policy (CVE-2014-0548).
  • A heap buffer overflow vulnerability that could lead to code execution (CVE-2014-0556, CVE-2014-0559).

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 access.

Actions: 

We recommend the following actions be taken:

  • 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.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
