Vulnerability Description
A remote code execution vulnerability has been discovered in the Windows Authenticode Signature verification for cabinet (.cab) file formats. A cabinet is a single file, usually suffixed with .CAB, that stores compressed files in a file library. A compressed file can be spread over several cabinet files. During installation, the setup application decompresses the files stored in a cabinet and copies them to the user's system. A remote attacker could exploit this vulnerability via a malformed CAB file. Successful exploitation of this vulnerability may allow execution of arbitrary code on a target system.

Vulnerability Details
The vulnerability is caused when the Windows Cabinet File Viewer omits fields from the file digest when signing and verifying a cabinet file.

Successful exploitation may allow the attacker to take complete control of a target system.
