Problems described in 
http://www.securityfocus.com/archive/1/378632
affect w3m browser too.  On 'gallery' samples from
http://lcamtuf.coredump.cx/soft/mangleme.tgz
w3m responds with  (there is a pause between the first and the second message)

Out of Memory!  Returning NIL!
Segmentation fault

for 'links_die1.html'. The reaction is the same for w3m-0.3.1-4.7x.1
from RH7.3 and w3m-0.5.1-4 from FC3test so likely this will show up 
in-between too. :-)  Other samples from the same source do not cause
troubles but who knows what else will.

Later versions of w3m may have _more_ troubles of that sort.  RH bugzilla ref:

FWIW, Red Hat has not released updates on this.
