libwpd vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 6.10
  • Ubuntu 6.06 LTS

Sean Larsson of iDefense Labs discovered that libwpd was vulnerable to
integer overflows. If a user were tricked into opening a specially
crafted WordPerfect document with an application that used libwpd, an
attacker could execute arbitrary code with user privileges.
