BBC covers Mac OS X ‘DMG bug’ – sort of

“The federal US computer security watchdog has issued a warning about a bug in Apple’s OS X operating system,” BBC News reports. “The US Computer Emergency Readiness Team (US Cert) issued the alert after security researchers produced code that could exploit the DMG bug. The flaw involves the way OS X handles disk images and could be used to crash or take over a vulnerable machine.”

The Beeb reports, “So far the DMG bug has only been shown to work under laboratory conditions and has not been seen in the wild…The bug has only been proved to work under laboratory conditions. No cases of it being exploited in the wild are known and no users are thought to be at risk. The availability of the exploit code might tempt some malicious hackers to craft webpages that take advantage of it… Users of Apple Mac computers are far less likely to suffer security problems because the vast majority of viruses are written to exploit Microsoft’s Windows operating system. There are also differences in the way that OS X works which help to prevent malicious code taking hold.”

The Beeb reports, “Apple has yet to provide a fix for the DMG bug though a workaround is known which should stop computers falling victim.”

Since the BBC, in their finite wisdom, neglect to explain the extremely simple “workaround” solution, we fill in their blank here: In Safari’s Preferences, uncheck the “Open ‘Safe’ files after downloading” box.

  1. I really wish people would write about tech issues in an accurate way. Not just about Apple but in general, the public are confused enough about technology that stuff like this doesn’t help one but. There is a genuine issue here, perhaps nothing major but still something people should know about, they should also know how bad it is, which at this stage is not very.

  2. In other news, Pfizt’her has created a mutant virus in the lab, not in the wild, but there are concerns that if this virus, created in a lab, not in the wild, were to somehow get out, then people should get inoculated, which in a related story, the same team has devised a vaccine.

  3. M.X.N.T.4.1,

    The problem is that “tech” journalists don’t seem to really understand the subject of their reporting. The people who do understand it, however, are too busy creating the next best thing to become tech journalists.

    I guess we’re stuck with what we’ve got :/

  4. BBC proving again their Microsoft love affair. Macs what are they.

    Check out this BBC interview with Woz. Interviewer seems to think Woz is an Apple executive!

    The link to the recording is on this page.. the linke entitled “Apple Boss”

    You’ll love the style over substance question, and the one, ‘why isn’t Apple more like Microsoft’. If I’d have been Woz I’d have been on the news for having flattened the man…!

    Incompetent BBC. Again. sigh

  5. The Beeb is anti-Mac. The problem with their Barbra Streisand is that Brits believe it. Here is the result of their poll.

    Should Mac users worry about computer security?

    Yes – 77.98%

    No – 22.02%

    Mac users shouldn’t ‘worry’ about security, they should just not open a dubious file from an unknown source.

  6. They say: “could be used to crash or take over a vulnerable machine”

    Not what I heard! Close to the first, sort of like the second, not precisely either. The thing can cause a spin-til-reboot pinwheel of death. So … it causes the user to “crash” their system to make it go away. And … it “takes over” your disk-mount/dismount ability. This is seriously annoying stuff, particularly to a Mac user unused to such bothersome behavior!

  7. I unchecked that option a long time ago. when you download a couple of hundred files in one session you sure as hell don’t want all of them opened ” width=”19″ height=”19″ alt=”smile” style=”border:0;” />

  8. BBC outsourced their IT to Siemens:,1000000308,39167296,00.htm

    and is in bed with Microsoft (I bet in a submissive role as well):

    with the Labour government standing next to the bed with the lubricant.

    Basically, anything the BBC reports from a tech point of view can be ignored as pro-Microsoft and pro-PC monopoly FUD.

    What would I do as a UK resident? I’d shut the BBC down and give the money back to the shareholders (i.e. me).

    Oh but yeah, I’m not actually a ‘shareholder’ as such am I?.

    I have to pay the yearly fee or face imprisonment and a fine, but I don’t actually ‘own’ the content that the BBC produce using MY licence fee.

    It was hard enough to get hold of it before (it was in Real format). Now it’ll be coated in a nice, thick, sickly-sweet coating of Microsoft DRM, I can’t get at it at all.

    Not that I want to, as most of it’s socialist-liberal propaganda, (BBC news), social-engineered kids TV to turn my poor kids into happy little submissive Labour voters (CBeebies), or mind-numbing, ‘keep-the-proles-nice-and-ignorant’ reality shows.

    They do get to sell MY CONTENT to ‘BBC World’ however (who then sell it around the world), but do I get a dividend from this (seeing as it was paid for with MY MONEY)? I do not. Who get’s this cash? the treasury (i.e. government).

    Sorry for the rant, but the BBC signify everything that’s wrong with the UK.
