Overview

There are critical vulnerabilities in Adobe Flash player and related software. Exploitation of these vulnerabilities could allow a remote, unauthenticated attacker to execute arbitrary code or cause a denial of service on a vulnerable system.

I. Description

Adobe Security Bulletin APSB07-12 addresses vulnerabilities in Adobe Flash Player and related software. Further information is available in the US-CERT Vulnerability Notes database.

Several operating systems, including Microsoft Windows and Apple OS X, have vulnerable versions of Flash installed by default. Systems with Flash-enabled web browsers are vulnerable. To exploit these vulnerabilities, an attacker could host a specially crafted Flash file on a web site and convince a user to visit the site.

II. Impact

A remote, unauthenticated attacker could execute arbitrary code with the privileges of the user, steal credentials, or create a denial-of-service condition. If the user is logged on with administrative privileges, the attacker could take complete control of an affected system.

III. Solution

Apply Updates

Check with your vendor for patches or updates. For information about a specific vendor, please see the Systems Affected section in the vulnerability notes or contact your vendor directly. If you get the flash player from Adobe, see the Adobe Get Flash page for information about updates.

Disable Flash

Users who are unable to apply the patch should disable Flash. Contact your vendor or see the US-CERT Vulnerability Notes VU#110297, VU#730785, or VU#138457 for more details.
