ITS ADVISORY NUMBER:
2012-083

DATE(S) ISSUED:
11/08/2012

SUBJECT:
Multiple Vulnerabilities in Apple QuickTime Could Allow Remote Code Execution

OVERVIEW:

Multiple vulnerabilities have been discovered in Apple QuickTime that could allow remote code execution. Apple QuickTime Player is used to play media files on Microsoft Windows and Mac OS X operating systems. These vulnerabilities can be exploited if a user visits or is redirected to a specially crafted webpage or opens a specially crafted file, including an email attachment, using a vulnerable version of Apple QuickTime Player. Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

SYSTEMS AFFECTED:

  • Apple QuickTime versions prior to 7.7.3 for Windows and Mac OS X

RISK:
Government:

  • Large and medium government entities: High
  • Small government entities: High

Businesses:

  • Large and medium business entities: High
  • Small business entities: High

Home users: High

DESCRIPTION:
Multiple remote code execution vulnerabilities have been discovered in Apple QuickTime that could allow remote code execution. These vulnerabilities can be exploited if a user visits or is redirected to a specially crafted webpage or opens a specially crafted file.

The vulnerabilities are as follows:

  • A buffer-overflow vulnerability exists in the handling of REGION records in PICT files. (CVE-2011-1374);
  • A memory-corruption issue exists in the handling of PICT files. (CVE-2012-3757)
  • A use-after-free issue exists in the QuickTime plugin's handling of the '_qtactivex_' parameters within an HTML object element. (CVE-2012-3751)
  • A buffer-overflow vulnerability exists in the handling of the transform attribute in the 'text3GTrack' elements. (CVE-2012-3758)
  • Multiple buffer-overflow vulnerabilities exist in the handling of the 'style' elements in the QuickTime TeXML files. (CVE-2012-3752)
  • A buffer-overflow vulnerability exists in the QuickTime plugin's handling of MIME types. (CVE-2012-3753)
  • A use-after-free issue exists in the QuickTime ActiveX control’s handling of the 'Clear()' method. (CVE-2012-3754
  • A buffer-overflow vulnerability exists in the handling of the Targa image files. (CVE-2012-3755)
  • A buffer-overflow vulnerability exists in the handling of the 'rnet' boxes in the MP4 files. (CVE-2012-3756)

Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

RECOMMENDATIONS:
We recommend the following actions be taken:

  • Apply appropriate updates provided by Apple to affected systems immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to download or open files from un-trusted websites.
  • Remind users not to open e-mail attachments from unknown users or suspicious e-mails from trusted sources.
  • Remind users not to click links from unknown sources, or to click links without verifying the intended destination.
