CVE-2011-1417

Status Candidate

Overview

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.

Zero Day Initiative Advisory 11-109

Zero Day Initiative Advisory 11-109 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari on the iPhone. 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 the support for parsing Office files. When handling the OfficeArtMetafileHeader the process trusts the cbSize field and performs arithmetic on it before making an allocation. As the result is not checked for overflow, the subsequent allocation can be undersized. Later when copying into this buffer, memory can be corrupted leading to arbitrary code execution under the context of the mobile user on the iPhone.
