1.  Bulletins Topics

    Sun announces the release of a new version of AnswerBook2 and patches
    which relate to security flaws in the http server included with 
    AnswerBook2.

    Sun recommends that you follow the directions in section 4 to
    upgrade your AnswerBook2 server and install the listed patch 
    immediately on all systems running AnswerBook2.

2.  Who is Affected
	
    AnswerBook2:
    
	Vulnerable:		Any systems running a version of AnswerBook2 
                                before 1.4.2.
				Answerbook2 version 1.4.2 without the 
				appropriate patch listed below.
    	Not vulnerable:		All systems not running AnswerBook2.
    	

3.  Understanding the Vulnerability

    Sun Solaris(tm) AnswerBook2 ships with an HTTP server (dwhttpd) 
    that allows users to access Solaris documentation using a web browser. 

    A vulnerability exists that allows a malicious user to access the 
    administration of AnswerBook2 as well as the ability to run arbitrary
    commands on the remote host as the webserver user (daemon).


4.  Corrective Action

    Two steps are required to protect against these vulnerabilities.

    Step 1)  Update AnswerBook2 to the latest version (at least version 1.4.2)
    The latest version of AnswerBook2 can be dowloaded from:

    http://www.sun.com/software/ab2/dwnld_versions.html

    Step 2)  Install the AnswerBook2 patch
	 
    Answerbook2 Version		Patch ID

    1.4.2			110011-02
