[Bug 1465014] Re: after update still vulnerable against LOGJAM

 

I think that site is simply printing the warning based on the browser
user agent, and not actually testing for the vulnerability.

logjam is planned to be officially addressed in Firefox 39, so it will
probably change once firefox 39 gets pushed out.

** Package changed: openssl (Ubuntu) => firefox (Ubuntu)

Title:
  after update still vulnerable against LOGJAM

Status in firefox package in Ubuntu:
  New

Bug description:
  Hint: http://www.ubuntu.com/usn/usn-2639-1/

  " As a security improvement, this update also modifies OpenSSL
  behaviour to reject DH key sizes below 768 bits, preventing a possible
  downgrade attack. "

  I installed the update but the test site says, i'm still vulnerable (see attachted screen shot).
