Caldera International, Inc. Security Advisory

Subject: Linux: temporary file races in libmm
Advisory number: CSSA-2002-032.0
Issue date: 2002 July 30
Cross reference:
______________________________________________________________________________


1. Problem Description

The OSSP mm library (libmm) allows a local Apache user to gain
privileges via temporary files, possibly via a symbolic link.


2. Vulnerable Supported Versions

System Package

3. Solution

The proper solution is to install the latest packages. Many
customers find it easier to use the Caldera System Updater, called
cupdate (or kcupdate under the KDE environment), to update these
packages rather than downloading and installing them by hand.

Isn't this list moderated?

Why do all vendors suddenly want to spam us with tons of *useless*
advisories, that we get anyhow?

didn't the post on bugtraq say that the new mailing list has been build
because securityfocus has gone commercial?

No, but it is a closed list. We allow posts from non-members based on
their merit and relevance.

We believe that the vendor notifications are useful information. To
provide a viable alternative to other more commercial lists, we need to
extend our reach to as wide a range of people as possible. I have been
campaigning for vendors to submit content to us for this reason.

Yes. I fail to see the commercialism in allowing vendors to post their
advisories. We're not making anything from it, and I doubt they are either.

Our original statement was questioning whether a commercial entity could
operate a mailing list such as this and remain unbiased, and more
importantly, not profit from the information (and early access to it)
themselves.

All of the above are well-documented in the (draft) list charter, available
at http://lists.netsys.com/full-disclosure-charter.html

I don't think so. Especially considering how quick your message
went through the list reflector. And especially with the
statement from the list home page: "We will try to operate this
list without moderation, as we feel moderation is an impediment
to communication."

Well, if you were running Caldera it wouldn't be that useless.
Or if you didn't already read the message on bugtraq/caldera's
announce list/etc.

And, of course, according to the list home page, the message is
on topic:
"This list is dedicated to full disclosure of any and all security
issues. Please feel free to discuss anything related to security."

Personally I'd prefer the vendor notifications to be put on a parallel
list, because
1. A flurry of 100s of one-man-and-their-dog Linux distributions
announcing a security update obscures the real discussion
(especially as each announcement is in its own thread).
2. I already get (multiple) copies of this stuff. Save the
electrons, give me a chance to not duplicate to that extent.

[.Damn, we're back to list meta discussions - this is the most
introspective list I have ever been on :-) ]
