VU#945060 - Adobe Macromedia Flash products contain multiple vulnerabilities

Several vulnerabilities in Adobe Macromedia Flash products may allow a remote attacker to execute arbitrary code on a vulnerable system.

Several operating systems, including Microsoft Windows (see Microsoft Security Advisory 916208), have vulnerable versions of Flash installed by default. Systems with Flash-enabled web browsers are vulnerable. An attacker could host a specially crafted Flash file on a web site and convince a user to visit the site.


A remote, unauthenticated attacker could execute arbitrary code with the privileges of the user. If the user is logged on with administrative privileges, the attacker could take complete control of an affected system. An attacker may also be able to cause a denial of service.


Apply Updates

Adobe has provided the updates for these vulnerabilities in APBS06-03.

Disable Flash

Please see Microsoft Security Advisory 916208 for instructions on how to disable Flash on Microsoft Windows. For other operating systems and web browsers, please contact the appropriate vendor.
