So this would mean that it will break some setups.

You're right, but the solution could be ask the user, during postinstall package configuration, to set SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION (and set it by default) explaining briefly the vulnerability. This wouldn't break anything existing but give the posibility to protect against vulnerability.

P.D.: the changelog link of openssl (http://packages.debian.org/changelogs/pool/main/o/openssl/openssl_0.9.8g-15+lenny5/changelog) is not working at the moment.
