Package : openvpn
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2005-3393 CVE-2005-3409
CERT advisory :
BugTraq ID : 15239
Debian Bug : 336751 337334

Several vulnerabilities have been discovered in OpenVPN, a free
virtual private network daemon. The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2005-3393

A format string vulnerability has been discovered that could allow
arbitrary code to be executed on the client.

CVE-2005-3409

A NULL pointer dereferencing has been discovered that could be
exploited to crash the service.

The old stable distribution (woody) does not contain openvpn packages.

For the stable distribution (sarge) these problems have been fixed in
version 2.0-1sarge2.

For the unstable distribution (sid) these problems have been fixed in
version 2.0.5-1.

We recommend that you upgrade your openvpn package.
