User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Ubuntu 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.
=========================================================== 
Ubuntu Security Notice USN-437-1             March 19, 2007
libwpd vulnerability
CVE-2007-0002
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.10
Ubuntu 6.06 LTS
Ubuntu 6.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 5.10:
  libwpd8c2                                0.8.2-2ubuntu0.1

Ubuntu 6.06 LTS:
  libwpd8c2a                               0.8.4-2ubuntu0.1

Ubuntu 6.10:
  libwpd8c2a                               0.8.6-1ubuntu0.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

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.
