Package : openvpn
Vulnerability : programming errors
Problem type : remote
Debian-specific: no
CVE ID : CAN-2005-2531 CAN-2005-2532 CAN-2005-2533 CAN-2005-2534
Debian Bug : 324167
Several security related problems have been discovered in openvpn, a
Virtual Private Network daemon. The Common Vulnerabilities and
Exposures project identifies the following problems:
CAN-2005-2531
Wrong processing of failed certificate authentication when running
with "verb 0" and without TLS authentication can lead to a denial
of service by disconnecting the wrong client.
CAN-2005-2532
Wrong handling of packets that can't be decrypted on the server
can lead to the disconnection of unrelated clients.
CAN-2005-2533
When running in "dev tap" Ethernet bridging mode, openvpn can
exhaust its memory by receiving a large number of spoofed MAC
addresses and hence denying service.
CAN-2005-2534
Simultaneous TCP connections from multiple clients with the same
client certificate can cause a denial of service when
--duplicate-cn is not enabled.
The old stable distribution (woody) does not contain openvpn packages.
For the stable distribution (sarge) these problems have been fixed in
version 2.0-1sarge1.
For the unstable distribution (sid) these problems have been fixed in
version 2.0.2-1.
We recommend that you upgrade your openvpn package.
