URI_DOTDOT_LOW_CNTRST false positives?

2015-03-16 Thread Per Jessen
I've recently upgraded to SA 3.4.0 - I'm seeing URI_DOTDOT_LOW_CNTRST
scoring on many legitimate mails. E.g. from linkedin and distrelec.

For instance:
http://files.jessen.ch/Tektronix-4-Kanal-Oszilloskop-deutlich-reduziert-TDS-2024C.eml

When the above was processed I noticed this in the log:

spamd[865]: dns: new_dns_packet (domain=chde..distrelec.com. type=A
class=IN) failed: a domain name contains a null label

As far as I can tell, the email above contains no such uri. 

I grep'ed a bit and found some more:

http://files.jessen.ch/more-dotdot.txt

I'm pretty certain 99% of those are false positives.  Probably a hiccup
on my installation, I was just wondering if anyone else is seeing this?

Which .cf file is this in?
Can't find it in SA trunk's .cf files.

John Hardin, your sandbox limit score of 2.5 seems sorta high..

I think the ruleset is from the tarball from the apache page.  Hmm, it
would appear to be quite old ?? 

http://mirror.reverse.net/pub/apache//spamassassin/source/Mail-SpamAssassin-rules-3.4.0.r1565117.tgz

Dated 20Feb2014. 

Is there a recent tarball somewhere?

iirc, that is the 3.4 release rules version

sa-update would provide the latest ruleset

Yup, got it.  Might not be a bad idea if the apache downloads page had a
link to the most recent rule-set too. (or even instead of the
original).

Anyway, problem solved, thanks.

your more-dotdot.txt log shows what could be a bug somewhere.

Pls open a bug & attach that log and the distrelec news eml with all 
relevant detail
if you have more verified sample msgs which don't include a .. in the 
URL yet log .., pls attach a few for dev team to work with.


Thanks

Yup, got it.  Might not be a bad idea if the apache downloads page had a
link to the most recent rule-set too. (or even instead of the
original).


for review before applying I often use

sa-update -D --updatedir /tmp/sa-work

This gets the latest tarball and unpacks the rules
Should be trivial to hack sa-update so it just gets the latest archive.

Putting on the downloads page means it has to be watched that all 
mirrors are in sync... the update mirrors are easier to control.



Anyway, problem solved, thanks.

My pleasure...
