 I wouldn't necessarily call this a vulnerability.  I ran into
 this when writting the Regex Scanner for QSQ.  Find
 $skip_text_msgs and set it to 0 so that all e-mails,
 including plain text, are scanned.

This only applies to the 1.2x versions, 1.1x don't have this feature.


You don't call this a vuilnerability??? What happens when the next virus outbreak comes in as inline uuencoded attachments instead of a jpeg like in my example and QS doesn't run virus scans on them because the message is plain text? Reformime wont even blow these messages apart...

[EMAIL PROTECTED] tmp]# reformime -i < msg1
section: 1
content-type: text/plain
content-transfer-encoding: 8bit
charset: iso-8859-1
starting-pos: 0
starting-pos-body: 771
ending-pos: 103899
line-count: 1693
body-line-count: 1677

So perlscanner will not help you when you try and block .pif or .exe
that are embedded inline...

I did not try ripmime to see if it pulls the inline uuencoding.

I know how to fix the damn thing..  But I really don't care at this
point because like I said, I don't use it yet.   I guess I just like to
look at code before throwing it onto something.

I just want everyone else to know that this is a problem with Q-S that
needs to be addressed before it is used in production environment.


What about installing "sharutils"?


From the rpm or from the source.

ftp://ftp.gnu.org/pub/gnu/sharutils/sharutils-4.2.1.tar.gz

Qmail-scanner has a routine for uudecode.

My server have not received any uuencode attachment in the last 10 weeks...

Cheers

Salvatore
