Systems Affected
* Adobe Flash Player 9.0.115.0 and earlier
* Adobe Flash Player 8.0.39.0 and earlier
Overview
Adobe has released Security advisory APSB08-11 to address multiple
vulnerabilities affecting Adobe Flash. The most severe of these
vulnerabilities could allow a remote attacker to execute arbitrary
code.
I. Description
Adobe Security Advisory APSB08-011 addresses a number of
vulnerabilities affecting the Adobe Flash player. Flash player
versions 9.0.115.0 and earlier and 8.0.39.0 and earlier are affected.
Further details are available in the US-CERT Vulnerability Notes
Database.
An attacker could exploit these vulnerabilities by convincing a user
to visit a website that hosts a specially crafted SWF file. The Adobe
Flash browser plugin is available for multiple web browsers and
operating systems, any of which could be affected.
II. Impact
The impacts of these vulnerabilities vary. The most severe of these
vulnerabilities allows a remote attacker to execute arbitrary code or
conduct cross-site scripting attacks.
III. Solution
Apply Updates
Check with your operating system vendor for patches or updates. If you
get the flash player from Adobe, see the Adobe Get Flash page for
information about updates.
Restrict access
These vulnerabilities can be mitigated by disabling the Flash plugin
or by using the NoScript extension to whitelist websites that can
access the Flash plugin. For more information about securely
configuring web browsers, please see the Securing Your Web Browser
document.
