      SCO Security Advisory

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.
