Hello, Mitch (WebCob) wrote: This is not an isolated case. The virus submission page must be changed to run the latest RELEASED version of clamav. Haven't looked in a while, but I think it should: Display result using latest RELEASE Display result using latest CVS Display IDENTITY of the virus Display config of the online scanner (in case this affects the result) Indicate time / date of the addition of this sig. This would eliminate confusion, and all the "it says detected but not what it is" etc. I volunteered to look at making changes like this as did a few others iirc, but for some reason this "tool" is not "open" :( Hopefully if enough people second the motion, the changes can at least be implemented. This could be done by writing PHP code to clamscan or better libclamav or clamd. Anyone knows how to write PHP extension ? For clamscan it could be a simple script invoking clamscan for scanning file stored in /tmp but it is quite dangerous.

[Clamav-users] 0.80rc bad format or broken data error - POSIX tar files
Hi, I see that a similar reported problem was fixed (RFC2298 fixes) but I have a slightly different problem. After some debugging, I can see that clamav doesn't seem to be able to scan POSIX tar archives (returns "Bad format or broken data ERROR") while GNU tar archives are fine. I used 'file' on the archive to determine what was what. Is this a ClamAV issue, or an OS issue - Redhat ES 3.0? If it's been fixed in RC3, then sorry - I cannot compile on this platform so am dependant on binary ports and there kind maintainers. -S --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

One of the major advantages of ClamAV over commercial products is that you are able to add your own signatures. Signatures for the JPEG exploit for non-80rc versions have been posted to the list. The only signatures in the new format in the current db are there because old style signatures would either produce false positives, or are not possible to create. There are less than 10 of them. The main advantage of the 0.80 version is the new unpackers and file type support. As such it is able to spot existing signatures in more file types. It does not inherently support a huge number of new signatures. The ClamAV team have very limited resources, and our time is better spent creating new signatures for unknown viruses, rather than wading through old viruses we already have signatures for, just because they happen to be in some archive type that old versions of clam don't know about. > > Maybe, development could be split into two parts: engine and program host. > Then updates to the engine (to accomodate new virus signature types) could > be added, while the program can be developed more slowly.

I've said this before, and I'll say it again. Thats a business decision on your part. You have to way up the pro and cons of the options and make a decision based on those. You can do things to mitigate the perceived risks of deploying the 0.80rc3 version, like doing internal testing, having an warm backup of your production system with which to continually test CVS versions (and supply feedback), re-configure your system to use clamscan rather than clamdscan, etc. Personally, I chucked 15GB of customer email through CVS versions prior to 0.80rc in order to check it's integrity. And continued to do so until I was happy with the results. As such I have confidence in it's stability. -trog signature.asc Description: This is a digitally signed message part

Hi everyone, BogusÅaw Brandys wrote: This is not an isolated case. The virus submission page must be changed to run the latest RELEASED version of clamav. Seconded. I run an up-to-date release version of ClamAV (0.75), there are virusses getting trough, but I can't submit them because 0.80rc3 would have recognised them. And we know clamav 0.75 would be able to detect these given specific examples.

Re: [Clamav-users] fetchmail & clamav-milter
Nigel, Sorry about that. The problem is that clamav-milter isn't scanning incoming mail. I want to configure it to scan mail that is passed to sendmail from fetchmail (running on the same host) to deliver to local mailboxes, but not scan outgoing mail. I agree, the documentation implies that leaving off the -o -f and -l switches should achieve this, but for some reason it's just not scanning anything [see the bottom of the mail log below]. I confirm that clamav-milter does indeed scan mail if the -o or -l switch is used. How does clamav-milter determine what is incoming, what is outgoing and what is lan mail (and pardon my ignorance)? Is it my sendmail configuration, perhaps?

Definitely read everything in the docs before attempting an install. I would also suggest using MailScanner as a wrapper for ClamAV (and Spamassassin if desired) as it makes things much easier. There is a tutorial for the raq4 at http://www.qitc.net/support/mailscanner/ but remember that it is a little dated and you will still need to read the current docs on all the various pieces to insure a successful install. People here, the SA list, and the MS list are more than willing to help as long as you are willing to do some reading before hand. FAQ's MAQ's and the install's and readme's from the packages would be a great place to start. AFAIK there is no iron-clad step-by-step tutorial that is kept up to date. It's been my experience that these programs are constantly evolving to keep up with the never ending changes in viruses and spam techniques. New releases (or release candidates) are being generated constantly and it does take a willingness to do some reading to keep up. I'm using MailScanner, ClamAV, and Spamassassin very successfully here. The authors and developers deserve much praise for their awesome products and continued development and support. The least we users can do is to do a little reading and research before asking basic questions. If you want something that runs out of the box and where someone will fix it for you if it breaks, I would suggest a commercial package. There are several out there that use the same packages I mention above. Hope this gets you on the right track.

The helo checks, blacklists and other sender/client checks are just generalisations for any type of junk email. They are not the ones that I was including in that assessment. The main types of checks that should be done are regarding the composition of the emails. For example, the ones you mention above, clsid and boundary checks, will stop a proportional amount of virus mails from getting any further. Then there are others, like iframe, executable extensions, certain aspects of html content, excessive header line lengths, to name but a few. A lot of the virus emails, as well as containing the virii themselves, also rely upon exploits or failings in the targeted MUA software to actually execute or mask the content until it is executed. That is why there are such a raft of 'mime sanitising' programmes available, Anomy and MimeDefang being prime examples. The scripts I use are homemade, building up gradually, (over the last few months), in finesse and precision. It isn't perfect, granted, but it is getting closer. The few it does tend to miss due to exploits or invalid/dubious composition are then subjected to virus scanning. It literally boils down to the fact that if some content/composition in an email is not encountered in legitimate emails, then the assumption of its contents not being legitimate and safe are ninety something percent. Any type of defensive system is built upon layers. The order of the layers is down to personal preference, but there should always be a minimum of two layers of defense for any given attack vector.

I also use greylisting on top of all of the methods you have above, and clam now catches single digits of viruses/week (granted, this mx only handles about 800-1000 emails/day, but scale appropriately).

Re: [Clamav-users] ERROR: JPEG.Comment
I'm unsure what type of camera originally took the pictures. But the original pictures DO NOT show as having a virus. After I put it through ImageMagick's "convert" (I make thumbnails) it then thinks it has the virus. Now, I'm pretty sure that ImageMagick isn't injecting a virus as many of the other thumbnails I make do not with the same exact binary report no virus. I was unaware of the submit feature. I just sent it in at the submit site as a false positive! :) Thanks, -- -bk Quoting Kevin Spicer <[EMAIL PROTECTED]>: > On Wed, 2004-09-29 at 05:34, Brandon Knitter wrote: > > I have a few images that seem to be flagged as virii, when they are not. > I'm > > taking an image that is considered fine (no virus), then when I process it > > through convert (ImageMagick) it thinks it's has the virus.

I run an up-to-date release version of ClamAV (0.75), there are virusses getting trough, but I can't submit them because 0.80rc3 would have recognised them. And we know clamav 0.75 would be able to detect these given specific examples. Your clairvoyance astounds me. You are free to add your own signatures to spot your samples. They almost certainly wouldn't catch any other samples of the same virus though. Same virus, or same exploit? We're asking for protection against viruses, not against exploits (we'd happily upgrade to 0.80rc3 for that). Or are you saying this virus is polymorphic? I asked that in my original email that started this thread, and got no response. Sounds like the webpage needs to be improved in the way another poster suggested: have it tell you which versins of clamav can catch the file.

Re: [Clamav-users] clamav-milter - user notification
I guess a better way of putting it is this. Here is a copy of what my inbox looks like: With 80RC3: [EMAIL PROTECTED] 9:00 Virus intercepted 1.5 k [EMAIL PROTECTED] 9:00 Virus intercepted 1.5 k With 75.1 [EMAIL PROTECTED] 8:50 Virus intercepted 1.6 k [EMAIL PROTECTED] 8:50 Virus intercepted 1.6 k With 75.1, the "From" address in the in-box showed the apparent sender. I find this usefull as in some cases it *IS* the real sender and they don't know they have a virus. As for the -o option, in setting it up, I understood it to scan outgoing mail as well. The servers I have this installed on are gateways for ALL smtp mail traffic and if one of my users gets a virus, I wanted it to be trapped before leaving my network. - Ken > On Wednesday 29 Sep 2004 01:46, Ken Jones wrote: >> All, >> >> I just upgraded from 75.1 to 80rc3.

Thought I would change this to a new thread to stop the thread purists becoming annoyed ;) Must admit, I couldn't agree more on that part. I do, however, block quite a few attachment types. When was the last time you saw a valid .scr or .pif in an email :) As Stephen Gran mentioned in his reply, greylisting is also very effective at dissuading the one shot wonder attempts, as they tend to try once or change the sender address each time, thereby never gaining a valid triplet, and it only causes a slight delay in mail delivery times. That is the point, however, that I am trying to make. There are a shedload of solutions that can whittle down the amount of virii that ever reach the filtering/scanning stage of an email system, and once the remaining few, (few in relative terms), reach the filtering scripts, you can whittle them down, by various methods, to an even smaller proportion, before they ever need to be virus scanned. A cascade of various options, applied in the correct sequence, can make a fairly good barrier to the virus ingress. Virii evolve, and are created more quickly, and in more variation, than exploits or workarounds are found for existing software and access enforcement methods. Thereby, filtering on the variables that change at a slower rate of pace, whether it be by greylisting, extension type, or software vulnerabilities, will generate a larger blockage rate than allowing the virii to get to a line of defence which has to be kept constantly upto date to catch the rapidly evolving nature of the problem. Blocking on the constants first, then variations, and then morphs last, will yield a greater blockage rate.

It's probably because you need to tell freshclam how to tell clamd that a new database update has occurred. Then the next time clamd is passed data it will force a database reload.

AW: [Clamav-users] virus submission problem
Hi > The main types of checks that should be done are regarding the composition of the emails. For example, the ones you mention above, clsid and boundary checks, will stop a proportional amount of virus mails from getting any further. Okay... already doing so. > Then there are others, like iframe, executable extensions, certain aspects of html content, excessive header line lengths, to name but a few. I cannot prevent such things. I have no way to tell my customers: "you may not send each other executables or html-files with frames." They would go somewhere else immediately. Also greylisting is no option, since it slows down email traffic and some of my customers use robots, which rely on these mails. For the same reason, excessive header line lengths need to work. Altogether, the point is, I may not drop or slow down legitimate mail. So I "simply" scan for viri. Regards, Steffen smime.p7s Description: S/MIME cryptographic signature

Steffen Heil wrote: > I cannot prevent such things. I have no way to tell my customers: "you > may not send each other executables or html-files with frames." They > would go somewhere else immediately. Just shifted the reply to this thread, Steffen. The iframe exploit, you are already discriminating against, as it is in the Clam database as: Exploit.IFrame.Gen I never meant to imply that you use draconian methods on any broad areas of email communication, but as you can see from the above, there are specific portions of a laden email which can only point to one designated purpose. I disagree, however, with ISP's or companies who use lax restrictions on email content, just to keep customers or staff happy. At the end of the day, maintaining a proper, healthy, and most of all, sociable system takes precedence over peoples whims. It is the same in any business. You do your best to meet your customers needs, but you never allow customers to dictate poor practice. If you generalise areas, then you are theoretically arguing against AV interception altogether. The 'html-files with frames' bit above is generalising. A specific combination is what you protect against, not a general range. > For the same reason, excessive header line lengths need to work. Long header lines are fine, but when they are above the maximum laid down in the RFC's? Why should someone send an email which violates the specs, and expect for it to be accepted without further ado? With regards to greylisting and SAV, and other such components, they are purely a business or preference decision. They do work, but at an offset cost. They are an extra line of defence, they are not compulsory. All the best, Matt --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

Dennis Peterson wrote: Since building and installing .80rc2 and then rc3, all the memory leaks are gone. You know, I just noticed that you're right :) I wouldn't call it "memory leaks" though, since it may be just high memory usage (remember the long "kernel: Out of Memory" thread?) But the point is clamd's memory usage is much lower now compared to what it was a few weeks ago. Where I was normally rebooting clamd several times a day when the size got out of control it now is running for days on end with no change in size. The not-so-busy server that I have now only use 9M, and the busiest one only use 19M here. Strangely enough I can't see anything that might point to this change of behaviour on Changelog. --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
