TITLE

plural Apple Product ImageIO Heap-based buffer overflow vulnerability

DESCRIPTION

Heap-based buffer overflow in ImageIO in CoreGraphics in Apple iTunes before 10.2 on Windows allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted International Color Consortium (ICC) profile in a JPEG image. Apple iTunes is prone to a heap-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. This issue affects the Apple Inc.'s CoreGraphics library. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. Versions prior to Apple iTunes 10.2 are vulnerable. Apple iTunes is a set of media player applications of Apple (Apple), which is mainly used for playing and managing digital music and video files. There is a heap buffer overflow vulnerability in the implementation. iDefense Security Advisory 03.02.11 http://labs.idefense.com/intelligence/vulnerabilities/ Mar 02, 2011 I. BACKGROUND Apple's CoreGraphics library is an API used to create and manipulate graphical elements. This API is used by many Apple applications, including the Safari browser on both Windows and Mac OS X. II. </br></br> This vulnerability occurs during the processing of an embedded International Color Consortium (ICC) profile within a JPEG image. A small block of heap memory may be allocated for processing certain profile data. An index value is used to reference locations within this heap block. The index value can be manipulated in a manner that results in multiple memory writes to locations outside the bounds of the heap allocated block. This condition may lead to arbitrary code execution. III. ANALYSIS Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the user viewing the JPEG image. To exploit this vulnerability, a targeted user must load a malicious JPEG image. An attacker typically accomplishes this via social engineering or injecting content into compromised, trusted sites. After the user visits the malicious Web page, no further user interaction is needed. IV. V. WORKAROUND iDefense is currently unaware of an effective workaround for this vulnerability, as it is not possible to disable the CoreGraphics Framework without major functionality loss. VI. VENDOR RESPONSE Apple Inc. has released patches which addresses this issue. For more information, consult their advisory at the following URL: http://support.apple.com/kb/HT4554 VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2011-0170 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.
