Description

Karol Weisek has reported a vulnerability in wv, which potentially can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the "wvHandleDateTimePicture()" function of the wv library when processing "DateTime" fields in a specially crafted Word document.

Successful exploitation requires that a user is tricked into opening a malicious Word document in HTML mode.

The vulnerability has been reported in version 0.7.4, and a slight variant in versions 0.7.5, 0.7.6, and 1.0.0.

Solution
An update is available via CVS.
