Don't rely only on a firewall to protect your network, because firewalls can be bypassed. EnGarde Secure Linux is a security-focused Linux distribution made to protect your users and their data. The security experts at Guardian Digital fortify every download of EnGarde Secure Linux with eight essential types of open source packages. Then we configure those packages to provide maximum security for tasks such as serving dynamic websites, high availability mail, transport, network intrusion detection, and more. The result for you is high security, easy administration, and automatic updates. The Community edition of EnGarde Secure Linux is completely free and open source. Updates are also freely available when you register with the Guardian Digital Secure Network. http://www.engardelinux.org/modules/index/register.cgi --- EnGarde Secure Linux v3.0.7 Now Available Guardian Digital is happy to announce the release of EnGarde Secure Community 3.0.7 (Version 3.0, Release 7). This release includes several bug fixes and feature enhancements to the Guardian Digital WebTool and the SELinux policy, several updated packages, and several new packages available for installation. The following reported bugs from bugs.engardelinux.org are fixed in this release: #0000067 SIMAP AND SPOP3 packages are built disabling plaintext auth Several other bugs are fixed in this release as well. New features include: * A new package (hwlister) which can be used to generate an inventory of all the hardware which comprises your system. This package is now installed by default with EnGarde Secure Linux. * PHP was re-build with cURL support and a race condition was fixed in shadow-utils. * The latest stable versions of: MySQL (5.0.22), apache (2.0.58), asterisk (1.2.8), bacula (1.38.9), imap (2004g), openssl (0.9.8b), php5 (5.1.4), postfix (2.2.10), snort (2.4.4), sudo (1.6.8p12), syslog-ng (1.6.11), vim (6.4.010), and zaptel (1.2.6). * Several new packages: - binstats (1.08) Binstats is a statistics generation tool for installed programs. It is also useful for cleaning up a system by helping find duplicate executables, unused libraries, statically linked binaries and duplicate man pages. - bitchx (1.1) BitchX is an IRC (Internet Relay Chat) client that is based on ircII (but heavily modified). It is ncurses based and allows the user to get onto IRC without requiring the use of GUI client. - bittorrent (4.9.2) Bittorrent is a scatter-gather network file transfer protocol used for distributing files. It works in the opposite method of regular downloads with regard to the fact that the more people are currently downloading a file using bittorrent, the faster it will go. - ethereal (0.99.0) Ethereal is a network protocol analyzer. This version is ncurses based and allows the user to examine and capture data from a live network. - hyperion (1.0.2) Hyperion is an IRC daemon that allows clients to connect to it. This is the server that is used by Freenode. - john (1.7.0.2) "John" is a password cracker whose primary purpose is to detect weak passwords in order to strengthen the overall security of a system. - libapache-mod_fcgid (1.09) mod_fcgid is an apache web server module that acts as a binary compatibility alternative to mod_fastcgi. It comes with a new process management strategy. - libapache-mod_mono (1.1.14) mod_mono is an apache web server module that provides ASP.NET support for the apache web server. - libapache-mod_security (1.9.3) mod_security is an apache web server module that acts as an intrusion detection and prevention engine for web applications. It acts as another line of defense between improperly coded applications and the webserver. - makejail (0.0.5) Makejail, in conjunction with binstats, determines which binaries a program is going to need to be chrooted and creates a chroot jail for it. - mc (4.6.0) Midnight Commander is a console based ncurses visual file manager similar to Norton Commander. It has the ability to handle archives, FTP site, and many other files built in. - paketto (1.10) The Paketto Keiretsu is a collection of tools that use new and unusual strategies for manipulating TCP/IP networks. scanrand is said to be faster than nmap and more useful in some scenarios. - psad (1.4.5) PSAD is a collection of utilities that work with the linux firewalling code (IPTables) to detect port scans and other suspect traffic. It also includes the ability to configure threshold levels based on how stringent your ruleset is. - slat (2.0) SLAT provides a systematic way of determining if your SE Linux policy achieves your desired security goal. This is a useful tool when creating or modifying SELinux policy. All new users downloading EnGarde Secure Linux for the first time or users who use the LiveCD environment should download this release. Users who are currently using EnGarde Secure Linux do not need to download this release -- they can update their machines via the Guardian Digital Secure Network WebTool module. http://www.linuxsecurity.com/content/view/123016/65/ ---------------------- Linux File & Directory Permissions Mistakes One common mistake Linux administrators make is having file and directory permissions that are far too liberal and allow access beyond that which is needed for proper system operations. A full explanation of unix file permissions is beyond the scope of this article, so I'll assume you are familiar with the usage of such tools as chmod, chown, and chgrp. If you'd like a refresher, one is available right here on linuxsecurity.com. http://www.linuxsecurity.com/content/view/119415/49/ -------- --> Take advantage of the LinuxSecurity.com Quick Reference Card! --> http://www.linuxsecurity.com/docs/QuickRefCard.pdf +---------------------------------+ | Distribution: Debian | ----------------------------// +---------------------------------+ * Debian: New motor packages fix arbitrary code execution 31st, May, 2006 Updated package. http://www.linuxsecurity.com/content/view/122940 * Debian: New typespeed packages fix arbitrary code execution 31st, May, 2006 Niko Tyni discovered a buffer overflow in the processing of network data in typespeed, a game for testing and improving typing speed, which could lead to the execution of arbitrary code. http://www.linuxsecurity.com/content/view/122948 * Debian: New lynx-cur packages fix several vulnerabilities 1st, June, 2006 Updated package. http://www.linuxsecurity.com/content/view/122956 * Debian: New xmcd packages fix denial of service 2nd, June, 2006 The xmcdconfig creates directories world-writeable allowing local users to fill the /usr and /var partition and hence cause a denial of service.
