Symantec Posts Fix To Vulnerability

An anonymous reader writes "Just a few days after it was discovered, Symantec has posted a fix to a critical flaw with its Antivirus software." From the article: "The eEye digital security firm reported the problem initially, and discovered it was present in the newest versions of the affected Symantec products. Further research noted by Symantec described the problem as a flaw that made the products vulnerable to a stack overflow. Once exploited, that overflow could have permitted an attacker to execute code on the machine, with System level rights. The issue was made worse by being one that impacted enterprise-level customers, big spenders that purchase hundreds or thousands of licenses depending on the size of the business. "

    Just a few days after it was discovered, Symantec has posted a fix to a critical flaw [CC] with its Antivirus software.

    So how long after they confidentially reported the problem to Symantec (as I'm sure they did) did it take them to fix it?

    Patched or not, the information presented here and in the pages linked therein make it clear that -- until all machines are patched -- there is a distinct possibility of an exploit getting through. To that end, I have no doubt some groups have been hot on the issue looking for the hole.

    The same page ^^^ implies that symantec released IPS signatures for their products. With that said, do any signatures exist for other IPS/IDS solutions (snort, etc) ? If so, I would very much like to utilize them until any possibility of a threat has passed.

    As long as we keep on using languages that allow the application to access memory directly, we will keep on having these problems. I know plenty of people will say, "program carefully", but that's like saying, "seatbelts are stupid. If we all just drove safely we wouldn't need seatbelts or airbags or bumpers."

    Yes, of course even in memory safe languages (Java, Python, etc) something somewhere needs to have memory access. That thing is the VM/interpreter. Fortunately there are very few areas of code in the VM that need to have memory access, so if you make those correct, then you can write a million lines of application code and know that there aren't any overflows in it.

    Their reputation as an anti-virus provider used to be second to none, now after bloated software and software bugs a lot of people are having second thoughts.

    I think they need to go back to square one and develop a product that is not going to give them a bad reputation if they want to stay competitive.

    After working with a lot of other anti-virus packages and seeing how un-invasive a good anti-virus package can be I refuse to use Symantec products anymore and to my clients I strongly recommend them change products when their license is up for renewal.

    If it wasn't for Symantec bundelling their software with OEM's I wonder how much of an impact they would have? Most uneducated people I do work for think of all anti-virus as "Nortons" and are amazed at how much their system performance improves when I replace it with something else.

    They used to have some good products 10 years ago, but I haven't seen a decent anti-virus release from them for a long time now.

      Oh give me a break. If this was open source, the whole community would be claiming victory and using this as an example of how quick problems are fixed.

      I thought that too.

      I've used Norton Firewall and Antivirus for over 6 years now. Guess what, in that 6 year period, I have never once had my computer compromised or any viruses infecting my computer. I'm a perfectly happy customer and will continue to trust my security with Norton whose entire reputation is dependent on the abilities of their software. IMO, that alone is what makes Norton a good company.

      Then you're a minority. Your one of two I've ever heard say that, as compared to over a hundred more people who've had to reinstall Windows because of Symantec's software. I'd had my first computer about a month in 2001, running Norton's, when it got owned by a worm that wrecked Windows so that I had to reinstall. It later got owned by another virus that also wrecked it so that I had to reinstall, it just did it more slowly. Not only that but there were other incidents related to viruses that caused me problems. Was I downloading stuff that had viruses? Not according to Norton's scanner. Finally, after I'd heard that AVG was good and free (I didn't know much about this stuff back then) I decided to give it a try. I scanned all the files on my computer and it found three OLD files that were viruses that always passed Norton's scan as clean. The youngest of these files was seven months! The oldest was 13 months. That's just plain incompentence on their part, as far as I'm concerned.

      Anyhow, after AVG I never had problems with a virus again. Of ocurse, that was urgent for only about another year as I switched to *nix later. Now viruses rarely concern me personally at all, only with regard to my customers who bring me their PCs to fix and anytime I fidn one with Norton's or McAfee's I install Avast (Win 2k/XP) or AVG (98/ME). Virtually all of them have reported that Avast or AVG did much better at catching virused files they had and weren't so invasive, so Norton's doesn't seem to have improved since I was using their products.

      Here's an idea: if you're so confident in Norton's, try uninstalling it, install AVG or Avast and scan all your backup files with it as well as your computer. You say that your system is clean and Norton's has kept it so, but how do you know? Why not check to make sure? Because if you've been using Norton's exclusively that long, I believe you most likely do have a trojan that you don't know about.

      Amen. I used to use Norton products exclusively for security. I finally stopped when Norton AntiVirus/Personal Firewall 2005 refused to activate on my laptop (admittedly with a very messed up install). I had a valid license, and the activation went through with no apparent problem. But after the 30 day trial period, it suddenly stopped working and said I need to activate. I used up my activation credits trying to get it to work. Symantec support was no help at all. I sort of gave up, but when I started to get viruses (virii?), I realized I had to have something and got Grisoft AVG Antivirus Free. To my surprise, the free program was better than the extremely overpriced Norton suite. Since then, I use AVG exclusively, and recommend it to everyone I know. The software is a 20 MB download as opposed to ~500 MB and takes 3 minutes instead of 30 to install. It doesn't even require a restart after the installation (and neither do updates, which seem to come nearly every day). And most importantly, my computer is faster. I hear people complaining all the time about slow computers, and Norton is always the problem (although more RAM generally wouldn't hurt). I'm planning to buy the paid version, just to support the great things Grisoft is doing.

      In my book, it's not a good sign if any program takes a half hour to install or uninstall.

    Was a time where we used the term "virus" to refer to a self replicating piece of code that didn't rely on exploits to move around. We used the term "worm" to refer to code that did rely on exploits. So even in the most secure operating environment you could still have a virus, but you couldn't have a worm. Of course, now-a-days everyone refers to viruses as worms and worms as viruses. As long as the operating system is performing actions on behalf of the user you will have software that does what the author wants but not what the user wants. The only real way to stop that is to make the user do everything themselves.. that is, it's completely impractical to stop. Stop-gap measures like virus/worm/spyware/malware detection, quarantine and elimination will always be necessary to mitigate the damage these nasties can do.
