> (1) CRITICAL: Apache Tomcat JK Web Server Connector Stack Overflow
> Affected:
> Apache Tomcat JK Web Server Connector 1.2.19
> Apache Tomcat JK Web Server Connector 1.2.20
> Apache Tomcat 4.1.34
> Apache Tomcat 5.5.20
> 
> Description: Apache Tomcat, a popular application server, contains a
> stack overflow vulnerability. An overlong URL (one greater than 4095
> bytes) could exploit this buffer overflow and execute arbitrary code
> with the privileges of the server process. The flaw stems 
> from an unsafe
> memory copy in the Apache Tomcat JK Web Server Connector component.
> Certain versions of Tomcat include vulnerable versions of 
> this component
> by default. Note that, because Tomcat is open source, 
> technical details
> for this vulnerability can be determined through source code analysis.
> 
> Status: Apache confirmed, updates available.

> (2) CRITICAL: WordPress Blogging Software Backdoor
> Affected:
> WordPress version 2.1.1 when downloaded between February 
> 25th, 2007 and
> March 2nd, 2007
> 
> Description: WordPress, a popular and widely-used blog application,
> contains a remotely-accessible backdoor. Backdoors are malicious code
> inserted into an application that allows an attacker to compromise the
> application by accessing it in a special, attacker-defined way. On
> February 25th, 2007, the source code for WordPress version 2.1.1 was
> altered to contain a backdoor. A specially-crafted string passed in an
> HTTP request in a variable named "ix" or "iz" will lead to remote code
> execution with the privileges of the web server process. Full 
> technical
> details are publicly available for this vulnerability and it can be
> assumed that this vulnerability is being actively exploited 
> in the wild.
> 
> Status: WordPress confirmed, updates available.

> (8) Solaris Telnet Worm
> Description: The Solaris Telnet vulnerability discussed in a previous
> issue of @RISK is being actively attacked in the wild by a worm. This
> worm can attack both x86- and SPARC-architecture systems. The worm
> attempts to compromise a vulnerable system and execute a large number
> of commands as either the "lp" or "adm" user, and then 
> proceed to infect
> other systems. Users are advised to disable telnet, if 
> possible. Sun has
> released an "inoculation" script that will remove the worm 
> from infected
> systems, and prevent re-infection by disabling the telnet service.
