[Bug 1510163] Re: Poodle TLS1.0 issue in Trusty (and Precise)

 

** Description changed:

- This issue is present in Trusty and Precise with the stock main gnutls -
- https://community.qualys.com/blogs/securitylabs/2014/12/08/poodle-bites-
- tls
- 
- If I switch cups to use gnutls28-dev on 14.04 the issue appears to go
- away according to ssllabs.   My test case is cups with SSL on.
- 
- Reproduction Steps:
- launch a new trusty VM 
- sudo apt-get install cups 
- Open /etc/cups/cupsd.conf and change just this one section 
- ... 
- # Only listen for connections from the local machine. 
- #Listen localhost:631 
- Listen /var/run/cups/cups.sock 
- 
- SSLPort 443 
- SSLOptions None 
- ServerAlias 127.35.213.162.lcy-02.canonistack.canonical.com 
- ... 
- Restart cups and then run the ssllabs test - https://www.ssllabs.com/ssltest/ 
+ [Impact] 
+ Gnutls is affected by the Poodle TLS exploit https://community.qualys.com/blogs/securitylabs/2014/12/08/poodle-bites-tls

+ [Test Case]
+ launch a new trusty VM
+ sudo apt-get install cups
+ Open /etc/cups/cupsd.conf and change just this one section
+ ...
+ # Only listen for connections from the local machine.
+ #Listen localhost:631

+ ...
+ Restart cups and then run the ssllabs test - https://www.ssllabs.com/ssltest/
+ 
+ [Regression Potential] 
+ This is a simple off by one error, that's fixed in all newer versions of gnutls.
