TITLE

Apple QuickTime fails to properly handle corrupt media files

DESCRIPTION

Heap-based buffer overflow in Apple Quicktime before 7.0.4 allows remote attackers to execute arbitrary code via a GIF image file with a crafted Netscape Navigator Application Extension Block that modifies the heap in the Picture Modifier block. 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. Apple From QuickTime Version that fixes multiple vulnerabilities in 7.0.4 Has been released.Arbitrary code may be executed by a remote third party, DoS You can be attacked. For more information, see the information provided by the vendor. QuickTime is prone to a remote heap-based overflow vulnerability. This issue presents itself when the application processes a specially crafted GIF image file. A successful attack can result in a remote compromise. Versions prior to QuickTime 7.0.4 are vulnerable. This flaw has proven to allow for reliable control of data on the heap chunk and can be exploited via a web site by using ActiveX controls. The heap can be overwritten in the Picture Modifier block. The block size calculate code such as: .text:66A339CC mov ax, [esi+0Ch] .text:66A339D0 xor ecx, ecx .text:66A339D2 mov [esp+34h+var_28], ecx .text:66A339D6 mov [esp+34h+var_24], ecx .text:66A339DA mov [esp+34h+var_20], ecx .text:66A339DE mov [esp+34h+var_1C], ecx .text:66A339E2 mov word ptr [esp+34h+var_10], cx .text:66A339E7 mov [esp+34h+arg_4], eax .text:66A339EB movsx eax, ax .text:66A339EE mov word ptr [esp+34h+var_10+2], cx .text:66A339F3 mov cx, [esi+8] .text:66A339F7 movsx edx, cx .text:66A339FA sub eax, edx .text:66A339FC movsx edx, word ptr [esi+6] .text:66A33A00 add eax, 3Eh .text:66A33A03 push edi .text:66A33A04 movsx edi, word ptr [esi+0Ah] .text:66A33A08 sar eax, 3 .text:66A33A0B lea ebx, [esi+6] .text:66A33A0E and eax, 0FFFFFFFCh .text:66A33A11 sub edi, edx .text:66A33A13 movsx edx, ax .text:66A33A16 mov [esi+4], ax .text:66A33A1A imul edi, edx The allocate code is : .text:66A33A68 push edi .text:66A33A69 call sub_668B5B30 But when it real process data to this memory, it use real decode data to write this memory but didn\xa1\xaft check this heap size.

An attacker can create a qtif file and send it to the user via email, web page, or qtif file with activex and can directy overflow a function pointer immediately used so it can bypass any stack overflow protection in systems such as xp sp2 and 2003 sp1. Technical Details: When Quicktime processes the data field of a qtif format file, it will copy it to the stack by a byte to a byte , but there is no proper checking, so it will cause a stack overflow in memory. And in this stack, there is a function pointer which will be used immediately when it pre byte copies, so we can use it to bypass any stack overflow protection, such in xp sp2 and 2003 sp1. The origin function point value is 0x44332211. We only need to overflow it to : 0x08332211, ensuring it didn't cause a crash before the 0x44 has been overflowed to 0x08. When it overflows to 0x08332211, we can execute code to 0x08332211, and can first use javascript to get this memory and set my code in it. call [esp+138h+arg_4] <- call a function point in the stack, but this point can be overflowed References QuickTime: QuickTime File Format http://developer.apple.com/documentation/QuickTime/QTFF/index.html Protection: Retina Network Security Scanner has been updated to identify this vulnerability. Vendor Status: Apple has released a patch for this vulnerability. The patch is available via the Updates section of the affected applications. This vulnerability has been assigned the CVE identifier CVE-2005-2340. Credit: Discovery: Fang Xing Greetings: Thanks to all the guys at eEye, and especially Karl Lynn's help.
