Microsoft's Jet crash: Zero-day flaw drops after deadline passes:

The Zero Day Initiative has gone public with an unpatched remote-code execution bug in Microsoft's Jet database engine, after giving Redmond 120 days to fix it. The Windows giant did not address the security blunder in time, so now everyone knows about the flaw, and no official patch is available.

The bug, reported to Microsoft on May 8 with a 120-day deadline before full disclosure, was described on Thursday by ZDI, here. It was discovered by Lucas Leong of Trend Micro Security Research.

The bad news: it's a remote-code execution vulnerability, specifically, an out-of-bounds memory write. The good news is that an attacker can only trigger the bug by tricking the victim into opening a specially crafted Jet file, and any arbitrary malicious code smuggled in the document is executed only with the user's privileges (we've all made sure that users don't have admin privilege, right?) The booby-trapped Jet file can also be opened using JavaScript, so someone could be fooled into viewing a webpage that uses JS to open the file, causing the code to run if it's picked up by the database.

The other good news is that the Jet database engine is not terribly well deployed: it's mostly associated with Microsoft Access and Visual Basic. However, if you are using it, you probably will want to stop users from opening any maliciously rigged files.

    Considering your preferred method of marketing your skills is waxing quixotic and sucking cock until you land the gig, I have to wonder, don't your prospective bosses worry about how you might go psychotic and bite their dicks off?

    I don't tell my employers until I've actually worked for them long enough that I can accurately gauge how they'll react to my informing them of my mental illness.

    My experience with doing so has been overwhelmingly positive. I don't tell everyone but I do tell most of them.
