Protect against Logjam attack with Apache 2.2.15

Hi all,

I read here: https://weakdh.org/sysadmin.html that in order to be protected against Logjam attack I should apply new configuration to httpd (after creating 2048 bit key).

The problem is that it's only supported in Apache 2.4.8 and beyond while RedHat's latest stable is 2.2.15.
Is there any back ported solution to this vulnerability (assuming I must use the RedHat's latest stable release of Apache)?

Regards,
Ben
