-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of IBM Lotus Notes Email Client. User
interaction is required to exploit this vulnerability in that the target
must open a malicious email attachment.

The specific flaw exists within the Lotus Notes file viewer utilizing
the KeyView SDK to render a malformed .wk3 document. The application
will mistrust a length used to allocate a buffer. Later, the application
will use a differently calculated length in a copy used to initialize
that buffer. This leads to a buffer overflow and can lead to code
execution under the context of the application.

-- Vendor Response:
Autonomy states:
Autonomy corrected the above issues in the patch releases of versions
10.10, 10.8, 10.4, 9.2, 7.4 of IDOL Keyview on February 28, 2010.
