Researchers have discovered a flaw in Microsoft’s Access database application that, if left unpatched, could impact up to 60% of U.S. businesses.
The flaw, discovered by the team at Mimecast, could lead to the unintended disclosure of sensitive information. Mimecast estimates some 85,000 businesses are at risk. So far, however, it does not believe any companies have been compromised.
The memory leak is very similar to one that was found in Microsoft Office last year. The application will randomly save pieces of data called memory elements into every file. Normally, this is just a fragment of useless content, but it could, on occasion be something sensitive, such as passwords or user information.
