From $URL:

The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA) is used for the ECDHE_ECDSA cipher suite, does not properly implement curves over binary fields, which makes it easier for context-dependent attackers to determine private keys via a timing attack and a lattice calculation.

Sorry, not sure how I missed this one before releasing the last OpenSSL GLSA. 

This issue was fixed in dev-libs/openssl-0.9.8s and dev-libs/openssl-1.0.0e:
http://cvs.openssl.org/chngview?cn=20895
http://cvs.openssl.org/chngview?cn=20894

GLSA vote: yes.
