The majority of our readers is between 15 and 40 years old. They are interested in current news from the Linux world, upcoming projects etc.

In each issue you can find information concerning typical use of Linux: safety, databases, multimedia, scientific tools, entertainment, programming, e-mail, news and desktop environments.


LinuxSecurity.com Feature Extras:

Open Source Tool of March: ZoneMinder - For January and February, we chose some of the staples of open source security (GnuPG and Nmap) as the tool of the month. And deservedly so; both have just celebrated their ten-year anniversary in the open source realm, a rare feat for any open source project, much less one founded on security.

But for the month of March, we wanted to move ahead and change gears. This month's Open Source Tool is no newbie for sure, but we bet that most of you reading haven't heard of it. While most Linux security tools deal with digital security, this month's tool is one of the few to cross that divide;

Welcome to Zone Minder, the Open Source Tool for March...

Meet the Anti-Nmap: PSAD - Introduction

Having a great defense involves proper detection and recognition of an attack. In our security world we have great IDS tools to properly recognize when we are being attacked as well as firewalls to prevent such attacks from happening. However, certain attacks are not blindly thrown at you - a good attacker knows that a certain amount of reconnaissance and knowledge about your defenses greatly increases the chances of a successful attack. How would you know if someone is scanning your defenses? Is there any way to properly respond to such scans? You bet there is...

Thank you for reading the LinuxSecurity.com weekly security newsletter. The purpose of this document is to provide our readers with a quick summary of each week's most relevant Linux security headline.

Debian: New krb5 packages fix multiple vulnerabilities (Mar 18)

Several remote vulnerabilities have been discovered in the kdc component of the krb5, a system for authenticating users and services on a network. An unauthenticated remote attacker may cause a krb4-enabled KDC to crash, expose information, or execute arbitrary code.

Debian: New backup-manager packages fix information disclosure (Mar 15)

Micha Lenk discovered that backup-manager, a command-line backup tool, sends the password as a command line argument when calling a FTP client, which may allow a local attacker to read this password (which provides access to all backed-up files) from the process listing.

Debian: New ldapscripts packages fix information disclosure (Mar 15)

Don Armstrong discovered that ldapscripts, a suite of tools to manipulate user accounts in LDAP, sends the password as a command line argument when calling LDAP programs, which may allow a local attacker to read this password from the process listing.

Debian: New dovecot packages fix privilege escalation (Mar 14)

Prior to this update, the default configuration for Dovecot used by Debian runs the server daemons with group mail privileges. This means that users with write access to their mail directory by other means (for example, through an SSH login) could read mailboxes owned by other users for which they do not have direct write access (CVE-2008-1199). In addition, an internal interpretation conflict in password handling has been addressed proactively, even though it is not known to be exploitable.

Multiple memory management flaws were found in the GSSAPI library used by Kerberos that could result in the use of already freed memory or an attempt to free already freed memory, possibly leading to a crash or allowing the execution of arbitrary code (CVE-2007-5901, CVE-2007-5971).

Mandriva: Updated unzip packages vulnerability (Mar 18)

Tavis Ormandy of Google Security discovered an invalid pointer flaw in unzip that could lead to the execution of arbitrary code with the privileges of the user running unzip. The updated packages have been patched to correct this issue.

Mandriva: Updated nagios packages fix multiple (Mar 18)

A buffer overflow in the check_snmp plugin allowed remote attackers to cause a denial of service via crafted snmpget replies (CVE-2007-5623). Cross-site scripting vulnerabilities in Nagios allowed remote attackers to inject arbitrary web script or HTML via unknown vectors to unspecified CGI scripts (CVE-2007-5624, CVE-2008-1360).

SuSE: evolution (SUSE-SA:2008:014) (Mar 14)

The function emf_multipart_encrypted() that is used to process encrypted messages is vulnerable to format-string bugs. This bug can be abused by a remote attacker to execute arbitrary code by sending a crafted encrypted eMail.


Ubuntu: MySQL vulnerabilities (Mar 20)

Masaaki Hirose discovered that MySQL could be made to dereference a NULL pointer. An authenticated user could cause a denial of service (application crash) via an EXPLAIN SELECT FROM on the INFORMATION_SCHEMA table. This issue only affects Ubuntu 6.06 and 6.10. (CVE-2006-7232) Alexander Nozdrin discovered that MySQL did not restore database access privileges when returning from SQL SECURITY INVOKER stored routines.
