August 3, 2012

• – CVE ID:
  CVE-2011-3458

• – CVSS:
  7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P

• – Affected Vendors:
  Apple

• – Affected Products:
  Apple QuickTime

• – Vulnerability Details:
  This vulnerability allows remote attackers to execute arbitrary code on
  vulnerable installations of Apple QuickTime Player. User interaction is
  required to exploit this vulnerability in that the target must visit a
  malicious page or open a malicious file.

The specific flaw exists within how the application parses a header
containing codec-specific data. When handling an error case, the
application will forget to initialize a pointer which will later be used in
a memory operation. This can lead to code execution under the context of
the application.

  Apple has issued an update to correct this vulnerability. More details can
