Details

libwv2 did not sufficiently check the validity of its input. Certain
invalid Word documents caused a buffer overflow. By tricking a user
into opening a specially crafted Word file with an application that
uses libwv2, this could be exploited to execute arbitrary code with
the user's privileges.

The only packaged application using this library is KWord.

Ubuntu 5.10
