[cisco-voip] openSSL and heartbleed

[Mehtab Shinwari]

Brian,

Is the script internal to Cisco? I would love to do some internal testing in my lab on a few different versions before I send notifications to our clients that have the affected versions.

In other words can I please have the script? :)

Here's what I found testing against 9.1.2.10000.28 with a slightly modified python script:
bmeade at ubuntu:~$ python vulnscript 10.3.11.250
Connecting...
Sending Client Hello...
Waiting for Server Hello...
 ... received message: type = 22, ver = 0301, length = 1012
Sending heartbeat request...
Unexpected EOF receiving record header - server closed connection
No heartbeat response received, server likely not vulnerable

This is assuming the released script is checking for the vulnerability properly.

I haven't seen one.  Currently trying to run the example python script against one of my clusters but having some trouble.

weird. for some reason i fixated on the date beneath the entry in the search listing which had 2011, which made more sense.

do you know if there is a more recent advisory?

I don't think that's the correct advisory.  That's a DoS vulnerability from 2004.

Does anyone know if/when Cisco will be coming out with a security advisory about Open SSL and heartbleed?
