Vulnerability Note VU#115729

Apple QuickTime fails to properly handle corrupt TGA images

Original Release date: 11 Jan 2006 | Last revised: 11 Jan 2006

Overview

Apple's QuickTime is a player for files and streaming media in a variety of different formats. A flaw in QuickTime's handling of Targa (TGA) image format files could allow a remote attacker to execute arbitrary code on a vulnerable system.

Description

Several types of overflow vulnerabilities exist in the way QuickTime handles files in the Targa (TGA) image file format. A specially crafted TGA image can allow an attacker to execute arbitrary code of their choosing with the privileges of the user running QuickTime or cause a denial of service. Apple's advisory on this issue states that a buffer overflow, integer overflow, or integer underflow error could be exploited by such a crafted image. Additional details about the underlying cause of these overflows are not known.

Note that this issue affects QuickTime installations on both Apple Mac OS X and Microsoft Windows operating systems.

Impact

An attacker with the ability to supply a maliciously crafted TGA file (.tga or .targa) could execute arbitrary code on a vulnerable system or cause a denial of service. The attacker-supplied code would be executed with the privileges of the QuickTime user opening the malicious file. The crafted TGA image may be supplied on a webpage or in email for the victim to select, or by some other means designed to encourage them to invoke QuickTime on the exploit image..
