EnGarde Secure Linux Security Advisory: rsync (Jan 25, 2002, 21:48)

arbitrary locations of the stack. This may potentially lead to a
remote root shell."
Conectiva Linux Security Announcement: rsync (Jan 25, 2002, 21:46)
"Sebastian Krahmer from SuSe did an audit on the rsync source
code and found several vulneranilities regarding the use of signed

attacker could exploit this to execute commands on the rsync
Obelix versus MobiliX: Legal Response Online Now (Jan 25, 2002, 20:37)
"The legal response (PDF, 22 pages in German) is online now .
The document describes the origin of the names Obelix (from
'obelisk') and MobiliX (from 'mobil' and 'UniX'). Many well known
names are used to show how widespread the suffix 'ix' is in the IT
business, e.g. often UniX derivates are named by this scheme. This
is followed by an analysis of the pronounciation and spelling of
the words Obelix and MobiliX, and whether they can be mistaken from
members of the IT business or not. As a conclusion the charge is

The Register: Net patent tax - W3C publishes new advice
(Jan 25, 2002, 18:48)
"The RAND addition was stalled after the issue blew up at the
end of September, with open source developers advocating the

Moglen, a compromise has been reached."
SuSE Security Announcement: rsync (Jan 25, 2002, 18:16)
"There exist several signedness bugs within the rsync program
which allow remote attackers to write 0-bytes to almost arbitrary
stack-locations, therefore being able to control the programflow
and obtaining a shell remotely. These bugs have been fixed."

Adam Wiggins: Open Source on the Business Desktop (Jan 25, 2002, 05:29)
"My employer, TrustCommerce, has been making a slow transition
to open source desktops over the past year. Today we have removed
almost all proprietary software from the company desktops, and
we're doing business just as well (and arguably better) than
before. Surprisingly, the majority of our customers are not members
of the open source community (though a good portion of them are).
In fact, most of our customers have no idea what the the terms
"Open Source" or "proprietary" mean, and would think we were crazy
if we took Richard Stallman's suggestion and rejected the many .doc
and .xls files that are sent to us each day."
