==================================================================== CERT-Renater Note d'Information No. 2009/VULN288 _____________________________________________________________________ DATE : 23/07/2009 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Systems running Adobe Flash Player, Adobe Reader, Adobe Acrobat. ====================================================================== http://www.adobe.com/support/security/advisories/apsa09-03.html ______________________________________________________________________ Security advisory for Adobe Reader, Acrobat and Flash Player Release date: July 22, 2009 Vulnerability identifier: APSA09-03 CVE number: CVE-2009-1862 Platform: All Platforms Summary A critical vulnerability exists in the current versions of Flash Player (v9.0.159.0 and v10.0.22.87) for Windows, Macintosh and Linux operating systems, and the authplay.dll component that ships with Adobe Reader and Acrobat v9.x for Windows, Macintosh and UNIX operating systems. This vulnerability (CVE-2009-1862) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being actively exploited in the wild via limited, targeted attacks against Adobe Reader v9 on Windows. We are in the process of developing a fix for the issue, and expect to provide an update for Flash Player v9 and v10 for Windows, Macintosh, and Linux by July 30, 2009 (the date for Flash Player v9 and v10 for Solaris is still pending). We expect to provide an update for Adobe Reader and Acrobat v9.1.2 for Windows and Macintosh by July 31, 2009 (the date for Adobe Reader for UNIX is still pending). Deleting, renaming, or removing access to the authplay.dll file that ships with Adobe Reader and Acrobat v9.x mitigates the threat for those products, but users will experience a non-exploitable crash or error message when opening a PDF that contains SWF content. Depending on the product, the authplay.dll that ships with Adobe Reader and Acrobat 9.x for Windows is typically located at C:\Program Files\Adobe\Reader 9.0\Reader\authplay.dll or C:\Program Files\Adobe\Acrobat 9.0]\Acrobat\authplay.dll. Windows Vista users should consider enabling UAC (User Access Control) to mitigate the impact of a potential exploit. Flash Player users should exercise caution in browsing untrusted websites. Adobe is in contact with Antivirus and Security vendors regarding the issue and recommend users keep their anti-virus definitions up to date. Users may monitor the latest information on the Adobe Product Security Incident Response Team blog at the following URL: http://blogs.adobe.com/psirt or by subscribing to the RSS feed here: http://blogs.adobe.com/psirt/atom.xlm. Affected software versions Adobe Reader and Acrobat 9.1.2 and earlier 9.x versions Adobe Flash Player 9.0.159.0 and 10.0.22.87 and earlier 9.x and 10.x versions Severity rating Adobe categorizes this as a critical update. ====================================================================== ========================================================= Les serveurs de référence du CERT-Renater http://www.urec.fr/securite http://www.cru.fr/securite http://www.renater.fr ========================================================= + CERT-RENATER | tel : 01-53-94-20-44 + + 151 bd de l'Hopital | fax : 01-53-94-20-41 + + 75013 Paris | email: certsvp@renater.fr + =========================================================
