Summary

Stack-based buffer overflow in the normify function in the rlm_pap module (modules/rlm_pap/rlm_pap.c) in FreeRADIUS 2.x, possibly 2.2.3 and earlier, and 3.x, possibly 3.0.1 and earlier, might allow attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long password hash, as demonstrated by an SSHA hash.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

"From Red Hat Security Advisory 2015:1287 :

Updated freeradius packages that fix one security issue, several bugs,
and add various enhancements are now available for Red Hat Enterprise
Linux 6.

Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

FreeRADIUS is a high-performance and highly configurable free Remote
Authentication Dial In User Service (RADIUS) server, designed to allow
centralized authentication and authorization for a network.

A stack-based buffer overflow was found in the way the FreeRADIUS
rlm_pap module handled long password hashes. An attacker able to make
radiusd process a malformed password hash could cause the daemon to
crash. (CVE-2014-2015)

The freeradius packages have been upgraded to upstream version 2.2.6,
which provides a number of bug fixes and enhancements over the
previous version, including :

* The number of dictionaries have been updated.

* This update implements several Extensible Authentication Protocol
(EAP) improvements.

* A number of new expansions have been added, including:
%{randstr:...}, %{hex:...}, %{sha1:...}, %{base64:...},
%{tobase64:...}, and %{base64tohex:...}.

* Hexadecimal numbers (0x...) are now supported in %{expr:...}
expansions.

* This update adds operator support to the rlm_python module.

* The Dynamic Host Configuration Protocol (DHCP) and DHCP relay code
have been finalized.

* This update adds the rlm_cache module to cache arbitrary attributes.

For a complete list of bug fixes and enhancements provided by this
rebase, see the freeradius changelog linked to in the References
section.

(BZ#1078736)

This update also fixes the following bugs :

* The /var/log/radius/radutmp file was configured to rotate at
one-month intervals, even though this was unnecessary. This update
removes /var/log/radius/radutmp from the installed logrotate utility
configuration in the /etc/logrotate.d/radiusd file, and
/var/log/radius/radutmp is no longer rotated. (BZ#904578)

* The radiusd service could not write the output file created by the
raddebug utility. The raddebug utility now sets appropriate ownership
to the output file, allowing radiusd to write the output. (BZ#921563)

* After starting raddebug using the 'raddebug -t 0' command, raddebug
exited immediately. A typo in the special case comparison has been
fixed, and raddebug now runs for 11.5 days in this situation.
(BZ#921567)

* MS-CHAP authentication failed when the User-Name and
MS-CHAP-User-Name attributes used different encodings, even when the
user provided correct credentials. Now, MS-CHAP authentication
properly handles mismatching character encodings. Authentication with
correct credentials no longer fails in this situation. (BZ#1060319)

* Automatically generated default certificates used the SHA-1
algorithm message digest, which is considered insecure. The default
certificates now use the more secure SHA-256 algorithm message digest.
(BZ#1135439)

* During the Online Certificate Status Protocol (OCSP) validation,
radiusd terminated unexpectedly with a segmentation fault after
attempting to access the next update field that was not provided by
the OCSP responder. Now, radiusd does not crash in this situation and
instead continues to complete the OCSP validation. (BZ#1142669)

* Prior to this update, radiusd failed to work with some of the more
recent MikroTIK attributes, because the installed directory.mikrotik
file did not include them. This update adds MikroTIK attributes with
IDs up to 22 to dictionary.mikrotik, and radiusd now works as expected
with these attributes. (BZ#1173388)

Users of freeradius are advised to upgrade to these updated packages,
which correct these issues and add these enhancements. After
installing this update, the radiusd service will be restarted
automatically."

    descriptionSeveral 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.
