tag_insight = "Lynx is a text-based Web browser.

  An arbitrary command execution flaw was found in the Lynx "lynxcgi:" URI
  handler. An attacker could create a web page redirecting to a malicious URL
  that could execute arbitrary code as the user running Lynx in the
  non-default "Advanced" user mode. (CVE-2008-4690)
  
  Note: In these updated lynx packages, Lynx will always prompt users before
  loading a "lynxcgi:" URI. Additionally, the default lynx.cfg configuration
  file now marks all "lynxcgi:" URIs as untrusted by default.
  
  A flaw was found in a way Lynx handled ".mailcap" and ".mime.types"
  configuration files. Files in the browser's current working directory were
  opened before those in the user's home directory. A local attacker, able to
  convince a user to run Lynx in a directory under their control, could
  possibly execute arbitrary commands as the user running Lynx. (CVE-2006-7234)
  
  All users of Lynx are advised to upgrade to this updated package, which
  contains backported patches correcting these issues.";
