SMB MS Windows GDI+ JPEG Overflow

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.

Description

This signature detects the transmission of a malicious JPEG file. The JPEG file can execute additional code on the system.

Additional Information

The Microsoft Graphics Device Interface (GDI+) library JPEG handler is prone to an integer underflow vulnerability when handling JPEG format images.

JPEG images are stored in what is known as the JPEG File Interchange Format (JFIF) specification that defines the actual structure of the file containing the image data. The Microsoft GDI+ is a successor to the Windows Graphics Device Interface (GDI), and is used by default in the Windows XP and Windows Server 2003 operating systems. The GDI+ library (gdiplus.dll) is responsible for parsing and displaying image files, such as JPEG files.

This vulnerability presents itself due to a lack of sufficient sanity checks performed when subtracting two from a value derived from a JPEG (JFIF) comment segment length. When ensuring that the target comment segment contains data, prior to carrying out a memory copy operation, the software subtracts two from the segment length to ensure that the value is not zero. However, the procedure does not verify that the length value is greater than or equal to two prior to the subtraction. As a result, by supplying a segment length value of zero or one, the subtraction operation will result in an integer underflow. The underflow will result in a segment length value of negative one or negative two.

When this erroneous segment length value is subsequently employed in the memory copy operation, excessive data is copied into an insufficient heap-based chunk of memory. This operation causes the corruption of heap-based memory management structures, and in turn assists the attacker in writing to arbitrary locations in process memory.

Symantec has confirmed that a specially crafted JPEG image may trigger this vulnerability and result in the execution of arbitrary, attacker-supplied code. Code execution would occur in the context of the user that is running software that is linked to the vulnerable library.

Because this issue affects a shared library, any software that is linked to the GDI+ library will be prone to this vulnerability. Additionally, third-party software may ship with a vulnerable version of the GDI+ library. This may lead to the re-introduction of the vulnerability on a system that has been patched against the issue. Diligence should be exercised when third-party image processing software is being installed.
