The following cyber advisory was issued by the New York State Office of Information Technology Services and is intended for State government entities. The information may or may not be applicable to the general public and, accordingly, the State does not warrant its use for any specific purposes.

ITS ADVISORY NUMBER:
2013-060

DATE(S) ISSUED:
7/09/2013

SUBJECT:
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution

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 11.7.700.224 and earlier versions for Windows
  • Adobe Flash Player 11.7.700.225 and earlier versions for Macintosh
  • Adobe Flash Player 11.2.202.291  and earlier versions for Linux
  • Adobe Flash Player 11.1.115.63 and earlier versions for Android 4.x
  • Adobe Flash Player 11.1.111.59 and earlier versions for Android 3.x and 2.x

RISK:
Government:

  • Large and medium government entities: High
  • Small government entities: High

Businesses:

  • Large and medium business entities: High
  • Small business entities: High

Home users: High

DESCRIPTION:
Adobe has released security updates for Adobe Flash Player that address vulnerabilities which could result in remote code execution. These security updates resolve the following vulnerabilities:

  • A heap buffer overflow vulnerability that could lead to code execution (CVE-2013-3344).
  • A memory corruption vulnerability that could lead to code execution (CVE-2013-3345).
  • An integer overflow when resampling a user-supplied PCM buffer (CVE-2013-3347). 

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.

RECOMMENDATIONS:
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.
