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.
