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in the OCSP feature in FreeRADIUS 2.1.11 where it does not verify the status of a certificate (e.g. if the certificate was revoked).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.

Statement:

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