Microsoft Unicode Scripts Processor Arbitrary Code Execution

Microsoft Unicode Scripts Processor Arbitrary Code Execution
Posted Dec 17, 2015
Authored by Secunia, Hossein Lotfi

On the 8th December 2015, Microsoft released Security Bulletin MS15-130 to fix a vulnerability in Unicode Scripts Processor component found by Secunia Research. The vector for a successful exploitation is a specially crafted "True Type Font" (TTF) file, which typically can be embedded in e.g. Microsoft Office documents or even in emails and web-based content depending on the font type. Successful exploitation could result in arbitrary code execution.

Vulnerability in Microsoft's Unicode Scripts Processor allows execution of arbitrary code

On the 8th December 2015, Microsoft released Security Bulletin MS15-130 [1] to fix a vulnerability in Unicode Scripts Processor component found by Secunia Research [2]. The Common Vulnerabilities and Exposures (CVE) project has assigned the CVE-2015-6130 identifier for the vulnerability.

The vector for a successful exploitation is a specially crafted "True Type Font" (TTF) file, which typically can be embedded in e.g. Microsoft Office documents or even in emails and web-based content depending on the font type.

The result is the execution of arbitrary code once successfully exploited and thus is rated as "Highly Critical" by Secunia Research.

Introduction:

Uniscribe is the Microsoft Windows set of services for rendering Unicode-encoded text, especially complex text layout. They are implemented in USP10.DLL. USP is an initialism for Unicode Scripts Processor [3].

Reproduction:

Open %systemroot%\Fonts\ariblk.ttf in a hex editor and change content of offset 0x4ED2 from 0x0014 to 0x011B.

Technical Details:

Note: The following analysis is done on Windows 7 SP1 with usp10.dll version 1.626.7601.18454.

During processing scripts in a font file, the code flow reaches the "LoadFont()" function within usp10.dll. Shortly after, this function calls the "GetFontDesc()" function to load mapping of character codes within the font.

Afterwards, a loop is entered to process available EncodingRecords. If platform ID is 3 and encoding ID is either 0 (Symbol) or 1 (Unicode BMP (UCS-2)) [4], then the offset and format of a table are saved in respective local variables.

After that, a loop is entered to check if there is an EncodingRecord offset larger than saved format 4 offset. If it is also smaller than cmap table data size, it is considered valid and will be saved.

.text:7603B242 next_record: ; CODE XREF: GetFontDesc(HDC__ *,int *,FONTCMAPDESC * *)+2E5_j
.text:7603B242 mov ecx, [eax] ; loading EncodingRecord offset

.text:7603B24F add eax, 8
.text:7603B252 sub esi, 1
.text:7603B255 jnz short next_record

Then, a subroutine is entered to change endianness of format 4 subtable. In order to calculate the length of operation, the saved offset from the last loop is subtracted from the original format 4 offset and to skip format and length fields (two short values), a subtraction by 4 is performed. Note that there is no check here for an integer underflow.
