This did not affect openssl packages in Red Hat Enterprise Linux 5 (based on upstream 0.9.8e) and openssl 1.0.0 packages in Red Hat Enterprise Linux 6 (i.e. packages released before RHBA-2013:1585, which rebased openssl from 1.0.0 to 1.0.1e).  Issue was introduced upstream in versions 0.9.8o and 1.0.0a via the following change:
