I took a brief look at the code. ECDH was introduced somewhere between
0.9.7 and 0.9.8. 0.9.7m doesn't have it (so it was never backported to
those stable releases), 0.9.8 does. The double-free bug, or at least
the code being patched now, is already present in 0.9.8.
Here's the trivial patch:
http://www.mail-archive.com/openssl-dev@openssl.org/msg28049.html
which should work for 0.9.8+ (applies cleanly to 0.9.8, with an offset)
and is not needed for older versions.
