Which linux OS do you have?
Some vendor Redhat/centos maintain the version while patching the security issues.  The notice is just informational.  Once you make sure that the openssl 0.9.7.x is patched, you can ignore those alerts.

The upgrade is simple enough, get the openssl source from www.openssl.org and configure/compile/install it.
The pitfalls however deal with whether the applications you have that use the openssl will continue to function with the newer version.
Some application had openssl statically compiled such that an install of the new version will not do a thing to secure/fix the issue.
ldd /path/to/mail_server_binary
If libssl is not part of the listing, that would mean that openssl is statically compiled and you would need to update the mail application.  i.e. recompile it with either the updated openssl 0.9.8 or the patched version 0.9.7.x
