Security
As reported last week, Evans
Data recently announced the results of a survey which indicated (among
other things) that 92% of their respondents have never suffered a virus
infection on their Linux systems. The mainstream press made a big deal out
of this result, but, to most Linux users, the interesting result was the
8%. Linux systems can have security problems, but virus problems, in
particular, are almost unheard of. An 8% infection rate seemed too high.
We dropped the folks at Evans Data a note asking for some more
information. The result came back from none other than Nick Petreley, who
is now the "Linux analyst" for Evans. He says:
The vast majority of Linux developers, 92%, have never experienced
a virus infection on Linux. We know of no known viruses to which
Linux is currently susceptible, so the tiny percentage of
respondents who claim to have experienced virus infections on Linux
servers may be referring to an historical incident. Although the
survey question does not account for this, it is also possible that
some respondents are referring to situations where they are using
Linux servers to filter viruses for Windows clients. In this case,
the viral infection may actually have taken place on a Windows
machine because the virus checker on the Linux server failed to
catch it
In other words, they don't really know either. The survey was performed
over the web (a private page accessible by invitation only) and didn't
really provide for detailed answers.

The various privacy implications of widespread use of radio-frequency
identification tags have been widely discussed. This eWeek
article, reporting on a Black Hat Briefings session, brings up a new
issue. It seems that the portion of most RFID tags which holds the product
code is rewritable. Anybody who can haul a suitably equipped system into a
store can rewrite the tags at will, creating no end of opportunities for
confusion and theft.
According to the article, things go even further than that:
And there's an even worse scenario: "It is only a matter of time
before someone puts a root exploit on one of these tags and hacks
into your supply chain," Grunwald said.
That scenario seems unlikely; the capacity of an RFID tag, and the uses to
which the tags are put, do not afford many opportunities for the injection
of shell code into point-of-sale systems. But, then, somebody might just
pull it off.
The real security risk is the number of systems which will be programmed to
believe what their RFID readers are telling them. It is surprising that a
device meant to be used as an identification token is rewritable in this
way. It should not take too long before troublemakers with RFID writers
convince the retail establishment that this was a bad decision.

Netcraft reports
that Internet scanning for servers running Secure Sockets Layer (SSL) has
spiked in the past week. " Security firms are advising network
administrators to install security patches for SSL servers, including a
recent update for mod_ssl, which is widely used in Apache servers running
OpenSSL. A security update was released July 16 to fix the vulnerability,
which may allow a remote attacker to execute arbitrary code when Apache is
configured to use mod_ssl and mod_proxy, according to an advisory from
Gentoo Linux."

CVE #(s): | CAN-2004-0415
|
| Created: | August 3, 2004 |
Updated: | October 26, 2004 |
| Description: |
Paul Starzetz discovered
flaws in the Linux kernel when handling file
offset pointers. These consist of invalid conversions of 64 to 32-bit file
