CVE-2011-2701

Publication date 4 August 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The ocsp_check function in rlm_eap_tls.c in FreeRADIUS 2.1.11, when OCSP is enabled, does not properly parse replies from OCSP responders, which allows remote attackers to bypass authentication by using the EAP-TLS protocol with a revoked X.509 client certificate.
