Mandriva Linux Security Advisory MDKSA-2005:206-1
http://www.mandriva.com/security/
_______________________________________________________________________

Package : openvpn
Date : December 9, 2005
Affected: 2006.0
_______________________________________________________________________

Problem Description:

Two Denial of Service vulnerabilities exist in OpenVPN. The first
allows a malicious or compromised server to execute arbitrary code
on the client (CVE-2005-3393). The second DoS can occur if when in
TCP server mode, OpenVPN received an error on accept(2) and the
resulting exception handler causes a segfault (CVE-2005-3409).

The updated packages have been patched to correct these problems.

Update:

Packages are now available for Mandriva Linux 2006.
