Package : wv
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2004-0645
Debian Bug : 264972

iDEFENSE discovered a buffer overflow in the wv library, used to convert and preview Microsoft Word documents. An attacker could create a specially crafted document that could lead wvHtml to execute arbitrary code on the victims machine.

For the stable distribution (woody) this problem has been fixed in version 0.7.1+rvt-2woody3.

We recommend that you upgrade your wv package.
