Release date: February 13, 2012

Vulnerability identifier: APSA13-02

CVE number: CVE-2013-0640, CVE-2013-0641

Platform: Windows and Macintosh

Summary

Adobe has identified critical vulnerabilities (CVE-2013-0640, CVE-2013-0641) in
Adobe Reader and Acrobat XI (11.0.01 and earlier), X (10.1.5 and earlier) and 
9.5.3 and earlier for Windows and Macintosh.  These vulnerabilities could cause
the application to crash and potentially allow an attacker to take control of
the affected system. 

Adobe is aware of reports that these vulnerabilities are being exploited in the
wild in targeted attacks designed to trick Windows users into clicking on a 
malicious PDF file delivered in an email message.

Adobe is in the process of working on a fix for these issues and will update
this advisory when a date for the fix has been determined.  

Affected software versions

    Adobe Reader XI (11.0.01 and earlier) for Windows and Macintosh
    Adobe Reader X (10.1.5 and earlier) for Windows and Macintosh

Mitigations

Users of Adobe Reader XI and Acrobat XI for Windows can protect themselves from
this exploit by enabling Protected View. To enable this setting, choose the 
"Files from potentially unsafe locations" option under the Edit > Preferences >
Security (Enhanced) menu.

Enterprise administrators can protect Windows users across their organization
by enabling Protected View in the registry and propagating that setting via GPO
or any other method. Further information about enabling Protected View for the
enterprise is available here.
