Comment 1 Vincent Danen 2009-03-27 18:56:31 UTC
This issue does not affect Red Hat Enterprise Linux 2.1, 3, 4, or 5.

Current stable Fedora versions (F9 and F10) were not affected too, as they ship openssl 0.9.8g and the affected functionality was only introduced in 0.9.8h.  Rawhide/F11 was affected (even though CMS is not enabled in the upstream sources by default, it is enabled explicitly in the Fedora spec file) and has already been updated to the fixed upstream version 0.9.8k.
