127 Research and Development: 127 Day!

[northern snowfall <dbailey27 () ameritech net>]

	Every year, 127 Research chooses an interesting topic, presenting it to 
our correspondants just to keep them up-to-date with our vastly 
increasing prowess and drive. This year will be the first we bring the 
public our yearly analysis. Focused on topics that challenge an 
analyst's skill, 127 Day releases display our level of ability in 
auditing, exploitation, theory, and more.
         This year, 2003, represents 127 Research and Development's 
first public 127-Day release! Our release covers the remote exploitation 
of the prescan memory corruption vulnerability found in versions of 
Sendmail earlier than 8.12.9. In the paper, Don Bailey touches on some 
interesting techniques not yet seen in public. One of these techniques 
is the misaligned-opcode method of text segment manipulation.
        The paper is viewable online in HTML format, as well as down-
loadable in portable Postscript. The exploit interface described in
the report is also available at 127's website.
