OpenSSL compliance with Linux distributions

[Patrick Mooc]

Hello,

I'm using an old version of OpenSSL (0.9.8g) on an old Linux Debian 
distribution (Lenny).

Is it possible to upgrade OpenSSL version without upgrading Linux Debian 
distribution ?
If yes, up to which version of OpenSSL ?

Are all versions of OpenSSL compliant with all Linux Debian distribution ?


Thank you in advance for your answer.

Best Regards,
