Description Mark J. Cox 2007-02-13 21:29:22 UTC

There is a DoS in apparantly all versions of spamassassin prior to
3.1.8 (which is not released yet).  A carefully crafted message can 
cause SpamAssassin to consume significant resources which could lead
to a DoS if an attacker sends many such messages:

Also affects RHEL4.

Patch here:
http://svn.apache.org/viewvc?view=rev&revision=507102

Comment 3 Josh Bressers 2007-02-14 03:58:22 UTC

I presume this flaw affects RHEL3 as well.  Is the plan to upgrade to
spamassassin 3.1.8, or to backport this fix?

Comment 5 Warren Togami 2007-02-14 22:04:48 UTC

It appears we lucked out.  RHEL3 is not effected in such a dangerous way.  Just
a slight delay, and no huge CPU or memory usage.  I suspect we need not touch it
for this CVE.  Will do further verification.

Upstream is releasing 3.1.8 today, and I am pushing it to Fedora now.
