A vulnerability in Adobe Flash Player may 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 allow an attacker to compromise data security, access confidential data, or compromise processing resources in a user's computer. Failed exploit attempts will likely cause denial-of-service conditions.
Adobe Flash Player 184.108.40.206 and earlier versions
Adobe Flash Player 220.127.116.11 and earlier 13.x versions
Adobe Flash Player 18.104.22.1688 and earlier versions for Linux
Vulnerable versions of Adobe Flash Player are prone to a vulnerability that could allow remote code execution due to an error in the handling of a dereferenced memory pointer (CVE-2014-8439).
Successful exploitation of this vulnerability 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 install programs; view, change, or delete data; or create new accounts with full user access.
We recommend the following actions be taken:
Install the updates provided by Adobe immediately after appropriate testing.
Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
