SecurityTracker Alert ID:  1026945
SecurityTracker URL:  http://securitytracker.com/id/1026945
CVE Reference:   CVE-2012-0752, CVE-2012-0753, CVE-2012-0754, CVE-2012-0755, CVE-2012-0756, CVE-2012-0767   (Links to External Site)
Date:  Apr 18 2012
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 11.1.102.55 and prior versions; 11.1.112.61 and prior for Android 4.x; 11.1.111.5 and prior for Android 2.x and 3.x
Description:   Multiple vulnerabilities were reported in Adobe Flash Player. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can conduct cross-site scripting attacks.

A remote user can create a specially crafted Flash content that, when loaded by the target user, will trigger a memory corruption error in a Windows ActiveX control and execute arbitrary code on the target system [CVE-2012-0751]. The code will run with the privileges of the target user.

A remote user can create a specially crafted Flash content that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target system [CVE-2012-0752, CVE-2012-0753, CVE-2012-0754]. The code will run with the privileges of the target user.

A remote user can create a specially crafted Flash content that, when loaded by the target user, will bypass security restrictions and execute arbitrary code on the target system [CVE-2012-0755, CVE-2012-0756]. The code will run with the privileges of the target user.

A remote user can cause arbitrary scripting code to be executed by the target user's browser [CVE-2012-0767]. The code will run in the security context of an arbitrary site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Xu Liu of Fortinet's FortiGuard Labs, Bo Qu of Palo Alto Networks, Alexander Gavrun (via TippingPoint's Zero Day Initiative), Eduardo Vela Nava of the Google Security Team, and Google reported these vulnerabilities.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with an arbitrary site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   Gentoo has issued a fix for CVE-2012-0752, CVE-2012-0753, CVE-2012-0754, CVE-2012-0755, CVE-2012-0756, and CVE-2012-0767.

Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

Multiple vulnerabilities in Adobe Flash Player, the worst of which
might allow remote attackers to execute arbitrary code.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

The Adobe Flash Player is a renderer for the SWF file format, which is
commonly used to provide interactive websites.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

    -------------------------------------------------------------------

    -------------------------------------------------------------------
  1  www-plugins/adobe-flash   < 11.2.202.228         >=3D 11.2.202.228

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Multiple vulnerabilities have been discovered in Adobe Flash Player.
Please review the CVE identifiers referenced below for details.

Impact
=3D=3D=3D=3D=3D=3D

A remote attacker could entice a user to open a specially crafted SWF
file, possibly resulting in execution of arbitrary code with the
privileges of the process or a Denial of Service condition.
Furthermore, a remote attacker may be able to bypass intended access
restrictions, bypass cross-domain policy, inject arbitrary web script,
or obtain sensitive information.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Adobe Flash Player users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=3Dwww-plugins/adobe-flash-11.2.202.228"
