Adobe Flash Player Integer Overflow



Adobe Flash Player is an application for viewing animations and movies using computer programs such as a Web browser; in common usage, Flash lets you put animation and movies on a website. Flash Player runs SWF files that can be created by the Adobe Flash authoring tool, by Adobe Flex, or by a number of other Macromedia and third-party tools.

Remote exploitation of an integer overflow vulnerability in Adobe Systems Inc.'s Flash Player could allow an attacker to execute arbitrary code with the privileges of the current user.

During the allocation of an array within a certain internal ActionScript function, a size calculation may cause an integer value to overflow. This condition may lead to the bounds of an undersized array being overflown during a memory copy operation. This can result in arbitrary code execution.


Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the user viewing the Web page. To exploit this vulnerability, a targeted user must load a malicious Flash file created by an attacker. An attacker typically accomplishes this via social engineering or injecting content into a compromised, trusted site.


The following Adobe Products are vulnerable:

  • Adobe Flash Player and earlier versions for Windows, Macintosh, Linux and Solaris operating systems
  • Adobe Flash Player and earlier versions for Android
  • Adobe AIR 2.7 and earlier versions for Windows, Macintosh and Android
