Adobe Updates for Multiple Vulnerabilities

Original release date: December 21, 2007
Last revised: --
Source: US-CERT

Systems Affected

* Adobe Flash Player 9.0.48.0 and earlier
* Adobe Flash Player 8.0.35.0 and earlier
* Adobe Flash Player 7.0.70.0 and earlier

Overview

Adobe has released Security bulletin APSB07-20 to address multiple
vulnerabilities affecting Adobe Flash Player. Attackers could exploit
these vulnerabilities to execute arbitrary code, perform DNS rebinding
and cross-site scripting attacks, conduct port scans, or cause a
denial of service.

I. Description

Adobe Security Update APSB07-20 addresses a number of vulnerabilities
affecting Adobe Flash 9.0.48.0 and earlier, 8.0.35.0 and earlier and
7.0.70 and earlier. Further details are available in the related
vulnerability notes.

An attacker could exploit these vulnerabilities by convincing a user
to load a specially crafted Flash file. Flash content is widely
deployed on the internet. An attacker could distribute Flash files
using web sites that allow user-supplied content, like popular social
networking sites.

II. Impact

The impacts of these vulnerabilities vary. An attacker may be able to
execute arbitrary code, perform DNS rebinding or cross-site scripting
attacks, conduct port scans, or cause a denial of service.

III. Solution

Upgrade Flash Player

Upgrade Flash Player according to the information in Adobe Security
bulletin APSB97-20. For the port scanning issue (CVE-2007-4324),
consider ActionScript network socket functionality per TechNote
kb402956.

Adobe provides a way to determine which version of Flash Player is
installed and a way to configure notifications of updates.
