ITS Advisory Number: 
2013-056
Date(s) Issued: 
Tuesday, June 11, 2013
Subject: 
A Vulnerability in Adobe Flash Player Could Allow for Remote Code Execution
Overview: 

Adobe has released a security update for 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 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. Failed exploit attempts will likely cause denial-of-service conditions.

Systems Affected: 
  • Adobe Flash Player 11.7.700.202 and earlier versions for Windows
  • Adobe Flash Player 11.7.700.203 and earlier versions for Macintosh
  • Adobe Flash Player 11.2.202.285  and earlier versions for Linux
  • Adobe Flash Player 11.1.115.58 and earlier versions for Android 4.x
  • Adobe Flash Player 11.1.111.54 and earlier versions for Android 3.x and 2.x
  • Adobe AIR 3.7.0.1860 and earlier versions for Windows and Macintosh
  • Adobe AIR 3.7.0.1860 and earlier versions for Android
  • Adobe AIR 3.7.0.1860 SDK & Compiler and earlier versions

Description: 

Adobe Flash Player is prone to an unspecified memory corruption vulnerability that could lead to code execution (CVE-2013-3343). This vulnerability can be exploited if a user visits a specially crafted webpage or opens a specially crafted file.

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 rights. Failed exploit attempts will likely cause denial-of-service conditions.

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