Sorry, based on your original description I was under the impression that you had upgraded from 8.04 to 10.04, rather than having just applied an update within the same release.
There was a recent SSL-related security update:
* SECURITY UPDATE: CRIME attack ssl attack (LP: #1068854)
- debian/patches/303_CVE-2012-4929.dpatch: backport SSLCompression
on|off directive. Defaults to off as enabling compression enables the
CRIME attack.
- CVE-2012-4929
