Description Vincent Danen 2011-07-21 21:38:06 UTC
DFN-CERT reported [1] a vulnerability in the OCSP feature in FreeRADIUS 2.1.11 where it does not verify the status of a certificate (e.g. if the certificate was revoked).

No further details, or a patch, were provided.  According to the changelog on the FreeRADIUS site [2], OCSP support was added in version 2.1.11:

* OCSP support from Alex Bergmann. See raddb/eap.conf, "ocsp" section.

Therefore earlier versions of FreeRADIUS are not affected by this flaw.

Not vulnerable. This issue did not affect the versions of freeradius as shipped with Red Hat Enterprise Linux 4, 5, or 6.
