Debian Bug     : 742820 789623 863673

Several issues were discovered in FreeRADIUS, a high-performance and
highly configurable RADIUS server.

CVE-2014-2015

    A stack-based buffer overflow was found in the normify function in
    the rlm_pap module, which can be attacked by existing users to
    cause denial of service or other issues.

CVE-2015-4680

    It was discovered that freeradius failed to check revocation of
    intermediate CA certificates, thus accepting client certificates
    issued by revoked certificates from intermediate CAs.

    Note that to enable checking of intermediate CA certificates, it
    is necessary to enable the check_all_crl option of the EAP TLS
    section in eap.conf. This is only necessary for servers using
    certificates signed by intermediate CAs. Servers that use
    self-signed CAs are unaffected.

CVE-2017-9148

    The TLS session cache fails to reliably prevent resumption of an
    unauthenticated session, which allows remote attackers (such as
    malicious 802.1X supplicants) to bypass authentication via PEAP or
    TTLS.

For Debian 7 "Wheezy", these problems have been fixed in version
2.1.12+dfsg-1.2+deb7u1.

We recommend that you upgrade your freeradius packages.
