The CMS_verify function in OpenSSL 0.9.8h through 0.9.8j, when CMS is
enabled, does not properly handle errors associated with malformed
signed attributes, which allows remote attackers to repudiate a
signature that originally appeared to be valid but was actually
invalid.

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.

Comment 4 Tomas Hoger 2009-03-30 08:18:37 UTC

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.
