By Behzad Najjarpour Jabbari, Senior Security Specialist On October 18, 2016, Oracle released an update for Oracle Outside-In Technology as part of the Oracle Critical Patch Update for October 2016 [1] to fix a heap-based buffer overflow and a use-after-free vulnerability that have been discovered by Secunia Research [2]. Both of which may ultimately result in a system compromise through an application that uses and exposes the affected functionality of Oracle Outside-In Technology and thus are rated as “Highly Critical” by Secunia Research. Additionally, Oracle addressed three further vulnerabilities discovered by Secunia Research that may result in a so-called "Denial of Service" (DoS) condition of an application using Oracle Outside-In Technology. This blog post focusses on the heap-based buffer overflow vulnerability. Product Background: Oracle Outside-In Technology provides software developers with a comprehensive solution to access, transform, and control the contents of over 500 unstructured file formats [3].

On October 18, 2016, Oracle released an update for Oracle Outside-In Technology as part of the Oracle Critical Patch Update for October 2016 [1] to fix a heap-based buffer overflow and a use-after-free vulnerability that have been discovered by Secunia Research [2]. Both of which may ultimately result in a system compromise through an application that uses and exposes the affected functionality of Oracle Outside-In Technology and thus are rated as “Highly Critical” by Secunia Research. Additionally, Oracle addressed three further vulnerabilities discovered by Secunia Research that may result in a so-called “Denial of Service” (DoS) condition of an application using Oracle Outside-In Technology. This blog post focusses on the heap-based buffer overflow vulnerability. Product Background: Oracle Outside-In Technology provides software developers with a comprehensive solution to access, transform, and control the contents of over 500 unstructured file formats [3]. This Oracle product is frequently bundled and used in many popular applications such as Microsoft Exchange, Novell GroupWise, and IBM WebSphere Portal. File Format Background: StarWriter files (SDW) are the default file format used by the StarWriter component of StarOffice versions prior to 5.x. Vulnerability Summary: The vulnerability is caused due to a boundary error within the “VwStreamRead()” function (vssdw.dll), which can be exploited to cause an out-of-bounds write memory access via a specially crafted SDW file and subsequently cause a crash of, or potentially execute arbitrary code within the context of, an application using the product Oracle Outside-In. The vulnerability is confirmed in version 8.5.3 (vssdw.dll version 8.5.3.1604151004). Technical Details: A fixed-size heap memory block gets allocated by “VwAllocProc()” function, which is being used while processing SDW files: .text:67AA1400 push esi .text:67AA1401 push 8FCh ; dwBytes .text:67AA1406 push 0 ; dwFlags .text:67AA1408 call ds:GetProcessHeap .text:67AA140E push eax ; hHeap .text:67AA140F call ds:HeapAlloc .text:67AA1415 mov esi, eax .text:67AA1417 test esi, esi .text:67AA1419 jnz short loc_67AA141D .text:67AA141B pop esi .text:67AA141C retn .text:67AA141D ; --------------------------------------------------------------------------- .text:67AA141D .text:67AA141D loc_67AA141D: ; CODE XREF: VwAllocProc+19 .text:67AA141D push 8FCh ; size_t .text:67AA1422 push 0 ; int .text:67AA1424 push esi ; void * .text:67AA1425 call memset .text:67AA142A add esp, 0Ch .text:67AA142D mov [esi+8F8h], esi .text:67AA1433 mov eax, esi .text:67AA1435 pop esi .text:67AA1436 retn .text:67AA1436 VwAllocProc endp The function “VwStreamRead()” uses and manages this memory block while processing the SDW file. After some initialization, the function tries to read the bitmap stream embedded in the SDW file: .text:67AA39F3 loc_67AA39F3: ; CODE XREF: VwStreamRead+13A4 .text:67AA39F3 mov eax, [esi+3Ch] .text:67AA39F6 dec dword ptr [eax] .text:67AA39F8 js short loc_67AA3A09 .text:67AA39FA mov ecx, [esi+3Ch] .text:67AA39FD mov eax, [ecx+10h] .text:67AA3A00 movzx edx, byte ptr [eax] .text:67AA3A03 inc eax .text:67AA3A04 mov [ecx+10h], eax .text:67AA3A07 jmp short loc_67AA3A17 .text:67AA3A09 ; --------------------------------------------------------------------------- .text:67AA3A09 .text:67AA3A09 loc_67AA3A09: ; CODE XREF: VwStreamRead+1378 .text:67AA3A09 push dword ptr [esi+3Ch] .text:67AA3A0C call sub_67AA3D90 .text:67AA3A11 add esp, 4 .text:67AA3A14 movsx edx, ax .text:67AA3A17 .text:67AA3A17 loc_67AA3A17: ; CODE XREF: VwStreamRead+1387 .text:67AA3A17 movzx eax, di .text:67AA3A1A inc edi .text:67AA3A1B mov [eax+esi+470h], dl .text:67AA3A22 test dl, dl .text:67AA3A24 jnz short loc_67AA39F3 This loop ends when it reaches a Null byte in the stream. As the stream is user-controlled and there are no boundary checks, it’s possible to trigger an out-of-bounds write memory access. By overwriting vftable pointers, it’s possible to change the application’s flow: .text:67AA3A59 lea ecx, [esi+470h] .text:67AA3A5F lea eax, [edi-2] .text:67AA3A62 mov [ecx], ax .text:67AA3A65 push dword ptr [esi+8F0h] .text:67AA3A6B mov eax, [esi+854h] .text:67AA3A71 push dword ptr [esi+8ECh] .text:67AA3A77 push ecx .text:67AA3A78 push edi .text:67AA3A79 push 326h .text:67AA3A7E call eax .text:67AA3A80 push dword ptr [esi+8F0h] .text:67AA3A86 mov eax, [esi+854h] .text:67AA3A8C push dword ptr [esi+8ECh] .text:67AA3A92 push 0 .text:67AA3A94 push 0 .text:67AA3A96 push 327h .text:67AA3A9B call eax .text:67AA3A9D push dword ptr [esi+8F0h] .text:67AA3AA3 mov eax, [esi+854h] .text:67AA3AA9 mov ebx, 1 .text:67AA3AAE push dword ptr [esi+8ECh] .text:67AA3AB4 push 0 .text:67AA3AB6 push 0 .text:67AA3AB8 push 325h .text:67AA3ABD call eax .text:67AA3ABF mov eax, 0E10h .text:67AA3AC4 add esp, 3Ch .text:67AA3AC7 cmp word ptr [esp+0D8h+var_C4], ax 0:000> g ModLoad: 777d0000 77830000 C:WindowsSysWOW64IMM32.DLL ModLoad: 75f40000 7600c000 C:Windowssyswow64MSCTF.dll ModLoad: 709c0000 709ea000 C:UsersbehzadDesktopvw-8-5-3-win-x86-32sdkdemoscclo.dll ModLoad: 709b0000 709bb000 C:UsersbehzadDesktopvw-8-5-3-win-x86-32sdkdemoSCCSD.DLL ModLoad: 709a0000 709ad000 C:UsersbehzadDesktopvw-8-5-3-win-x86-32sdkdemoSCCXT.DLL ModLoad: 70990000 70999000 C:UsersbehzadDesktopvw-8-5-3-win-x86-32sdkdemovssdw.dll (c04.f64): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling.
