TITLE

Apple QuickTime of QTVR Movie File Handling Heap-Based Buffer Overflow Vulnerability

DESCRIPTION

Heap-based buffer overflow in the QuickTime VR extension 7.2.0.240 in QuickTime.qts in Apple QuickTime before 7.3 allows remote attackers to execute arbitrary code via a QTVR (QuickTime Virtual Reality) movie file containing a large size field in the atom header of a panorama sample atom. Apple QuickTime is prone to a heap-based buffer-overflow issue because it fails to perform adequate boundary checks on user-supplied data. An attacker can exploit this issue by enticing an unsuspecting user to open a specially crafted movie file. Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the user running the application. Failed exploit attempts likely result in denial-of-service conditions. This issue affects Apple QuickTime running on Microsoft Windows Vista, Microsoft Windows XP SP2, and Mac OS X. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 National Cyber Alert System Technical Cyber Security Alert TA07-310A Apple QuickTime Updates for Multiple Vulnerabilities Original release date: November 06, 2007 Last revised: -- Source: US-CERT Systems Affected Vulnerabilities in Apple QuickTime affect * Apple Mac OS X * Microsoft Windows Overview Apple QuickTime contains multiple vulnerabilities.

These can be exploited by untrusted Java applets to disclose sensitive information or to execute arbitrary code with escalated privileges when a user visits a web page containing a malicious Java applet. 5) A boundary error in the processing of PICT image files can be exploited to cause a stack-based buffer overflow when a user opens a specially crafted PICT image file containing an invalid length for the "UncompressedQuickTimeData" opcode. 6) Errors exist in the parsing of Poly type opcodes (opcodes 0x0070-74) and the PackBitsRgn field (Opcode 0x0099) when processing PICT image files. The vulnerabilities are reported in QuickTime prior to version 7.3. SOLUTION: Update to version 7.3.

BACKGROUND QuickTime is Apple's media player product used to render video and other media. For more information visit http://www.apple.com/quicktime/ QuickTime VR (virtual reality) is a type of image file format supported by Apple's QuickTime. It allows the creation and viewing of photographically captured panoramas and the exploration of objects through images taken at multiple viewing angles. http://www.apple.com/quicktime/technologies/qtvr/ II. When processing panorama sample atoms, the size field in the atom header is not validated. QuickTime will copy the specified amount of memory to a fixed-size heap buffer, causing heap corruption. III. This could be accomplished by persuading the user to click a direct link to a malicious VR movie file. Additionally, this vulnerability could be exploited within a malicious web page. IV. DETECTION iDefense Labs confirmed this vulnerability exists in QuickTime VR extension 7.2.0.240 as included in QuickTime Player 7.2. Previous versions are suspected to be vulnerable. V. WORKAROUND Disabling the QuickTime plug-in for browsers can mitigate Web page attack vectors. To do this, uncheck the "Play movies automatically" setting within the QuickTime preferences Browser->Playback tab. VI. VENDOR RESPONSE Apple has released QuickTime 7.3 which resolves this issue. More information is available via Apple's QuickTime Security Update page at the URL shown below. http://docs.info.apple.com/article.html?artnum=306896 VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2007-4675 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.
