[German<\/a>]Microsoft released a fix for the Microsoft JET Database Engine bug on November 2, 2017. This update fixes the problem with the Access or Excel database connection, but not in all versions of Windows. Here are some details about the topic.<\/p>\n

<\/p>\n

The Background<\/h2>\n

\"\"There was a buffer overflow vulnerability in the Microsoft JET Database Engine that allowed a remote code execution attack. The attacker was able to install programs, view, modify or delete data, and create new accounts with full user privileges. However, users whose user accounts are configured to work with default permissions were less likely to be affected than users with administrator privileges.<\/p>\n

\"\"Microsoft has detailed this vulnerability in Security Advisory CVE-2017-0250<\/a> (last revision October 10, 2017). In August 2017 Microsoft releases some security updates for some Windows version to close this vulnerability (see Patchday August 2017: Updates for Windows 7\/8.1<\/a>).<\/p>\n

Issues since October 2017 patchday<\/h2>\n

On October 10, 2017 Microsoft released another patch, that causes issues. I received this comment<\/a>, mentions trouble accessing Excel files from Access.<\/p>\n

Since the last window supdate 10.10.2017, it is no longer possible to link excel files to Access 2000, or to open linked excel files.<\/p><\/blockquote>\n

Other comments within my blog confirmed an Excel data base access error. Microsoft was aware of this issue, as the following text indicates :<\/p>\n

Issue where applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) fail when creating or opening Microsoft Excel .xls files. The error message is, \"Unexpected error from external database driver (1). (Microsoft JET Database Engine)\".<\/p><\/blockquote>\n

Microsoft patches only some Windows builds<\/h2>\n

On November 2, 2017 Microsoft released a couple of extra ordinary updates, some are addressing the Microsoft JET Database Engine bug. Here are the updates:<\/p>\n
