Debian: DLA-977-1 Critical: FreeRADIUS Buffer Overflow and TLS Issues

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
