Subject:                OpenServer 6.0.0 : Vim ModeLines Further Variant 
Arbitrary Command Execution Vulnerability
Advisory number:        SCOSA-2006.13
Issue date:             2006 March 16
Cross reference:        fz533037
                        CVE-2005-2368 
______________________________________________________________________________


1. Problem Description

        Vim is susceptible to an arbitrary command execution
        vulnerability with ModeLines. This issue is due to insufficient
        sanitization of user-supplied input.
        
        By modifying a text file to include ModeLines containing the
        'glob()', or 'expand()' functions with shell metacharacters,
        attackers may cause arbitrary commands to be executed.
        
        This vulnerability allows an attacker to execute arbitrary
        commands with the privileges of the vim user. This gives
        an attacker the ability to gain remote access to computers
        running the vulnerable software.
        
        The Common Vulnerabilities and Exposures project
        (cve.mitre.org) has assigned the name CVE-2005-2368 to
        this issue.
