Debian: libapache-mod-ssl Advisory

Author: JT Smith

Debian: “Ed Moyle recently found a buffer overflow in Apache-SSL and mod_ssl.
With session caching enabled, mod_ssl will serialize SSL session
variables to store them for later use. These variables were stored in
a buffer of a fixed size without proper boundary checks.

Package        : libapache-mod-ssl, apache-ssl
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no

Ed Moyle recently found a buffer overflow in Apache-SSL and mod_ssl.
With session caching enabled, mod_ssl will serialize SSL session
variables to store them for later use.  These variables were stored in
a buffer of a fixed size without proper boundary checks.

To exploit the overflow, the server must be configured to require client
certificates, and an attacker must obtain a carefully crafted client
certificate that has been signed by a Certificate Authority which is
trusted by the server. If these conditions are met, it would be possible
for an attacker to execute arbitrary code on the server.

This problem has been fixed in version 1.3.9.13-4 of Apache-SSL and
version 2.4.10-1.3.9-1potato1 of libapache-mod-ssl for the stable
Debian distribution as well as in version 1.3.23.1+1.47-1 of
Apache-SSL and version 2.8.7-1 of libapache-mod-ssl for the testing
and unstable distribution of Debian.

We recommend that you upgrade your Apache-SSL and mod_ssl packages.

wget url
	will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

Lycoris Desktop/LX: New Linux distro for new Linux users

Author: JT Smith

John Gowin tells us of his review of the new Lycoris Linux distribution: “At first I was a little confused. For starters, the plastic clamshell case containing the installation CD was eerily reminiscent of those awful AOL packages I get regularly in my mail. I was also expecting to see the new Lycoris brand name, but was instead greeted with redmondlinux personal as the label on the package. (I was informed later via email from Joseph Cheek, CEO and founder of Lycoris that the next run of CDs will include the company name change.) The documentation included with the CD was a simple Installation Guide, which covered the basics for getting the distribution installed. The Guide was very clear and concise, but a little short on any useful troubleshooting information. This was a bit of foreshadowing though, because this distribution has one smooth installer.” You can read the review here at Linux Orbit.

The General Public License: It’s not just about Open Source

Author: JT Smith

Builder.com offers a critique about the GPL. “Attorney David Loundy’s clients never meant for their database to be free software or for its code to be open source. But when a database contractor used snippets of code copyrighted by the GNU General Public License (GPL), the clients were shocked to find they couldn’t sell their own software as a proprietary work.”
