    85 CVE-listed security vulnerabilities in Acrobat and Reader

    Given the quality of previous Adobe security fixes, there will now be at least another 85 new vulnerabilities for the hackers to find.

        FoxIt Reader

        I left Adobe Reader earlier this year and installed FoxIt Reader instead. WOW - what a difference - fast, easy to use, and FAST!

        And FoxIt doesn't "helpfully" hook into the rest of my computer. No more does my CPU and hard drive churn when I just single-click on a PDF in Windows Explorer (I don't even open the damned PDF and Adobe still likes to get involved.)

          Re: FoxIt Reader

          There are 100's of alternative PDF readers out there. Probably 20+ readers/editors.

          PDF is just the format for a file that can be rendered somewhat faithfully.

          The readers/editors will all have potential faults in how they handle strange stuff in the incoming file. Each one might be subject to compromise. Don't think that Adobe is the only bad actor, just because it has usually been so.

            Re: FoxIt Reader

            I was a fan of FoxIt for many years until the update frequency got incredulous. I switched to Sumatra which seems identically speedy and either less bug-ridden, or less updated (grin)

        Re: For @#&% Sake,

        Nope. The format is actually quite nice. I handle them daily, and have no problems whatsoever.

        What IS painful is the most common software combo to handle them – Windows, Office, and Adobe's Acrobat Reader. The irony is that Adobe's free software is one of the worst, given that it was Adobe that developed the format.

      Re: For @#&% Sake,

      there are at least 2 alternatives I'm aware of [atril and evince] and they run on Linux and FreeBSD [although evince may have mono dependencies now, DAMMIT - I use an older version of evince on windows machines, however, and so maybe it's there but I didn't notice]

      in any case, PDF is well supported in the open source world. We don't need Adobe's "special sauce" nor their attempts at *SLURP* [why ask me to LOG IN using my E-MAIL ADDRESS just to view a PDF file????]

      So yeah, toss Adobe's reader in to the trash and get something that actually WORKS! Atril is my current favorite. That may change if they do something stupid (like include mono dependencies).

      Re: For @#&% Sake,

      Firefox and Chrome(ium) both display PDFs natively, so there's another two possibilities which are available for a range of OS's

    I am amazed...

    ...that they just keep coming, after all these years.

    If you add them up there's probably two critical bugs per actual line of code. That takes dedication.

    / It's actually quite impressive how badly this software has been written

  5. John70

    It'll probably cost less to delete all the source code and start again from scratch and this time leave out all the bloat.

      dozens of new holes patched

      I suppose new holes means bugs that are not present in older versions of Acrobat Reader.

    How many holes does Adobe software ship with? If they know it's this buggy, what are they doing about it prerelease?

      Adobe Intern: "Err.. here are the fixes for the 85 bugs in Acrobat and Reader you gave me."

      Adobe Manager: "It took you long enough, I gave you that job over an hour ago!"

      Intern: "Sorry! What happens now? Do the changes get reviewed and tested?"

      Manager: "Ooh hark at you! 'Reviewed and tested'! This is Adobe! We don't need to do nonsense like that, especially since none of them are being targetted in the wild! Now here are 200 bug reports for Flash run-time. I need them fixing before lunch!"

        Too true. So many of these companies get rid of the good & well paid people so they can replace them with cheap interns.

    > Fortunately, Adobe said that none of the bugs was currently being targeted in the wild - yet.

    So is there any sort of backup for lofty bullshit like this? Or is it just "nobody emailed us to tell us they're using this exploit"?

      Nah, all the bad'uns are still using the fifty odd exploits from last month.

    85 new reasons to do it

    IMPRESSIVE (click bait). So, I've bitten: I can match that, but I have (at least) four reasons NOT to install Adobe Reader in the first place:

    1. size of installation file, then the size it takes on my hard drive, all over the place

    2. what it does to my registry, trying to be "helpful" without asking (not to me, that's for sure!)

    3. time it takes to open a single, FUCKING 1 MB pdf. It's like firing an Apollo 11 rocket to get to local Tesco

    4. every now and then read about 85 reasons to patch it

    Solution: find a free pdf software that's none of 1 - 4 and live happily ever after. Software such as? Well, google be thy friend! The End.

    Adobe PDF Software?

    Ummm.... Don't have it...

    I'm on a Mac, which means everything on my machine can handle PDF without the need to install anything, from Adobe or elsewhere (it has been declared one of the essential file formats by Apple ages ago).

    Yeah, sure, Apple's software (in particular Preview, which pretty much acts as Mac's Adobe Reader equivalent) has its own share of problems. I'm still a smug bastard about this in particular. I have a LOT less trouble (practically zero) with PDFs than with, say, .doc/.docx. ;)

      Your choice of icon is completely appropriate for anything with vi bindings.

        From the point of view of a non-vi user, it makes no sense, yes.

        But if you are vi-able, it makes perfect sense to lean toward applications with vi bindings across as much of the ui as possible.

    This is annoying and interesting

    Annoying as I've just learnt a bit more about Group Policy so played with trying to deploy Adobe DC (that was a mistake. Although ended up finding a good guide). Got it working so annoying that now need to apply a patch. But interesting as can now see what an update does to the deployment.

    Plenty of alternatives to the sluggish monster that is Acrobat Reader. I really avoid using it at the moment. I am also always annoyed at how it wants to "save changes" to a PDF presentation (made using pdflatex), in which I have edited exactly NOTHING in Acrobat Reader. What does it feel it needs to change to the file? Does it want to add ads? Custom malware? I seriously doubt any addition made by Acrobat Reader would be useful to me in even the widest sense of the word.

    Adobe Reader used to be quite good

    But that was about ten years ago.

    My bet is that the majority of these new vulnerabilities are in the "enhancements" and new features that Adobe keeps adding to try and hook users into their infrastructure. One of the issues that I have with the modern environment is that the manufacturers are far more interested in trying to get users hooked on their products than writing secure, bug-free software - nobody seems to care about that any more.

      No. No it didn't. It was always terrible. I was there, I remember.

    Quick question since I haven't used this in a decade.... Does it still attempt to back everything to the cloud... ie the Adove servers?

    1. dajames Silver badge

      Re: Enhancement?

      Does it still attempt to back everything to the cloud... ie the Adove servers?

      It seems to, yes ... though I only use the Android version (because I haven't yet found time to locate an Android PDF viewer that isn't worse -- suggestions please!).

      On a recently reset tablet I reinstalled Adobe Reader and was horrified to be confronted with a screen that invited me to sign in to the Adobe Cloud (using a Google, Facebook, or Adobe ID). It took me a while to notice a small, subtle, cross in the top corner of the screen that let me bypass that crap and open the PDF.

    Stopped using acro%^$7 when I found...

    that it searched the whole bloody file-system. A stale NFS mount stalled it, that's how I noticed.

    mupdf needs to be mentioned here, the fastest pdf reader I have met so far: with simple pdfs it can render at a rate of 100 per second on a decent machine. pdf-movies are possible and totally fun.

    I am a completely normal person, thank you for asking -------->

      Re: Stopped using acro%^$7 when I found...

      "that it searched the whole bloody file-system"

      I became 'slurp-aware' when pre-installed Adobe reader on a reconditioned windows 7 machine asked me for an e-mail address to register with their online services, EVERY! STINKING! TIME! I tried to use it.

      The possibility that they're ALSO scanning your network is VERY, VERY, DISTURBING...

      [what we need is actual confirmation of their data slurp so that no doubts will remain]

    I uninstalled everything Adobe years ago, Flash and Acrobat. I highly recommend everyone else do the same.

    The only reason I have Oracle JavaRE installed is for a single home automation controller console interface, otherwise JRE is disabled by default.

  20. mark l 2 Silver badge

    I ditched Acrobat in about 2009 as discovered that there are other much better free software out there to read PDFs.

    On the rare occasion I need to edit the content of a PDF document, Libreoffice will open PDF's and let you edit them should you want to. Although the rendering can get messed up with the document uses fonts not present on your computer.

    No thanks

    Got rid of everything Adobe years ago, seemed bloated and slow.

    Don't like their cloud 'ransom ware' offerings for photgraphers either.

  22. Lostintranslation

    I am curious to know whether these 85 flaws have always been in the software or have been recently introduced to make up for the holes that have already been patched?

    It's obviously useful to *someone* to have a piece of software that is almost universally installed on Windows machines and is so exploitable.

  23. Tree

    Acrobat Reader 4.0 was the last good version

    The older versions are not BLOATWARE and don't connect to unknown serves on the internet. 2.2 megabytes for version 4.0. Much harder to hack than recent bloated Adobe products.

    No problem for me. I just use Acrobat X standard and let the world go by.
