Integer overflow in QuickLook, as used in Apple Mac OS X before 10.6.7 and MobileSafari in Apple iOS before 4.2.7 and 4.3.x before 4.3.2, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a Microsoft Office document with a crafted size field in the OfficeArtMetafileHeader, related to OfficeArtBlip, as demonstrated on the iPhone by Charlie Miller and Dion Blazakis during a Pwn2Own competition at CanSecWest 2011.

The version of iWork 9.x installed on the remote Mac OS X host is earlier than 9.1. As such, it is potentially affected by several vulnerabilities :

  - A buffer overflow in iWork's handling of Excel files in     Numbers may lead to an application crash or arbitrary     code execution. (CVE-2010-3785)

  - A memory corruption issue in iWork's handling of Excel     files in Numbers may lead to an application crash or     arbitrary code execution. (CVE-2010-3786)

  - A memory corruption issue in iWork's handling of     Microsoft Word files in Pages may lead to an     application crash or arbitrary code execution.
    (CVE-2011-1417)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
