 desc = 'The remote host is affected by the vulnerability described in GLSA-200511-09
(Lynx: Arbitrary command execution)


    iDefense labs discovered a problem within the feature to execute
    local cgi-bin programs via the "lynxcgi:" URI handler. Due to a
    configuration error, the default settings allow websites to specify
    commands to run as the user running Lynx.
  
Impact

    A remote attacker can entice a user to access a malicious HTTP
    server, causing Lynx to execute arbitrary commands.
  
Workaround

    Disable "lynxcgi" links by specifying the following directive in
    lynx.cfg:
    TRUSTED_LYNXCGI:none

    http://www.idefense.com/application/poi/display?id=338&type=vulnerabilities


Solution: 
    All Lynx users should upgrade to the latest version:
    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/lynx-2.8.5-r2"
  

Risk factor : Medium
