CVE-2010-3696 1 Freeradius 1 Freeradius 2023-02-12 4.3 MEDIUM N/A
The fr_dhcp_decode function in lib/dhcp.c in FreeRADIUS 2.1.9, in certain non-default builds, does not properly handle the DHCP Relay Agent Information option, which allows remote attackers to cause a denial of service (infinite loop and daemon outage) via a packet that has more than one sub-option. NOTE: some of these details are obtained from third party information.
CVE-2005-4744 1 Freeradius 1 Freeradius 2023-02-12 6.4 MEDIUM N/A
Off-by-one error in the sql_error function in sql_unixodbc.c in FreeRADIUS 1.0.2.5-5, and possibly other versions including 1.0.4, might allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by causing the external database query to fail. NOTE: this single issue is part of a larger-scale disclosure, originally by SUSE, which reported multiple issues that were disputed by FreeRADIUS. Disputed issues included file descriptor leaks, memory disclosure, LDAP injection, and other issues. Without additional information, the most recent FreeRADIUS report is being regarded as the authoritative source for this CVE identifier.
CVE-2019-10143 3 Fedoraproject, Freeradius, Redhat 3 Fedora, Freeradius, Enterprise Linux 2023-02-12 6.9 MEDIUM 7.0 HIGH
** DISPUTED ** It was discovered freeradius up to and including version 3.0.19 does not correctly configure logrotate, allowing a local attacker who already has control of the radiusd user to escalate his privileges to root, by tricking logrotate into writing a radiusd-writable file to a directory normally inaccessible by the radiusd user. NOTE: the upstream software maintainer has stated "there is simply no way for anyone to gain privileges through this alleged issue."
CVE-2022-41859 1 Freeradius 1 Freeradius 2023-01-24 N/A 7.5 HIGH
In freeradius, the EAP-PWD function compute_password_element() leaks information about the password which allows an attacker to substantially reduce the size of an offline dictionary attack.
CVE-2022-41861 1 Freeradius 1 Freeradius 2023-01-24 N/A 6.5 MEDIUM
A flaw was found in freeradius. A malicious RADIUS client or home server can send a malformed abinary attribute which can cause the server to crash.
CVE-2022-41860 1 Freeradius 1 Freeradius 2023-01-24 N/A 7.5 HIGH
In freeradius, when an EAP-SIM supplicant sends an unknown SIM option, the server will try to look that option up in the internal dictionaries. This lookup will fail, but the SIM code will not check for that failure. Instead, it will dereference a NULL pointer, and cause the server to crash.
CVE-2019-17185 2 Freeradius, Opensuse 2 Freeradius, Leap 2022-04-22 5.0 MEDIUM 7.5 HIGH
In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BN_CTX instance to handle all handshakes. This mean multiple threads use the same BN_CTX instance concurrently, resulting in crashes when concurrent EAP-pwd handshakes are initiated. This can be abused by an adversary as a Denial-of-Service (DoS) attack.
CVE-2019-13456 4 Freeradius, Linux, Opensuse and 1 more 4 Freeradius, Linux Kernel, Leap and 1 more 2022-01-01 2.9 LOW 6.5 MEDIUM
In FreeRADIUS 3.0 through 3.0.19, on average 1 in every 2048 EAP-pwd handshakes fails because the password element cannot be found within 10 iterations of the hunting and pecking loop. This leaks information that an attacker can use to recover the password of any user. This information leakage is similar to the "Dragonblood" attack and CVE-2019-9494.
CVE-2015-9542 3 Canonical, Debian, Freeradius 3 Ubuntu Linux, Debian Linux, Pam Radius 2020-08-14 5.0 MEDIUM 7.5 HIGH
add_password in pam_radius_auth.c in pam_radius 1.4.0 does not correctly check the length of the input password, and is vulnerable to a stack-based buffer overflow during memcpy(). An attacker could send a crafted password to an application (loading the pam_radius library) and crash it. Arbitrary code execution might be possible, depending on the application, C library, compiler, and other factors.
CVE-2017-10985 1 Freeradius 1 Freeradius 2019-10-02 7.8 HIGH 7.5 HIGH
An FR-GV-302 issue in FreeRADIUS 3.x before 3.0.15 allows "Infinite loop and memory exhaustion with 'concat' attributes" and a denial of service.
CVE-2017-10986 1 Freeradius 1 Freeradius 2019-10-02 5.0 MEDIUM 7.5 HIGH
An FR-GV-303 issue in FreeRADIUS 3.x before 3.0.15 allows "DHCP - Infinite read in dhcp_attr2vp()" and a denial of service.
CVE-2017-10982 1 Freeradius 1 Freeradius 2019-10-02 5.0 MEDIUM 7.5 HIGH
An FR-GV-205 issue in FreeRADIUS 2.x before 2.2.10 allows "DHCP - Buffer over-read in fr_dhcp_decode_options()" and a denial of service.
CVE-2017-10981 1 Freeradius 1 Freeradius 2019-10-02 5.0 MEDIUM 7.5 HIGH
An FR-GV-204 issue in FreeRADIUS 2.x before 2.2.10 allows "DHCP - Memory leak in fr_dhcp_decode()" and a denial of service.
CVE-2017-10987 1 Freeradius 1 Freeradius 2019-10-02 5.0 MEDIUM 7.5 HIGH
An FR-GV-304 issue in FreeRADIUS 3.x before 3.0.15 allows "DHCP - Buffer over-read in fr_dhcp_decode_suboptions()" and a denial of service.
CVE-2017-10980 1 Freeradius 1 Freeradius 2019-10-02 5.0 MEDIUM 7.5 HIGH
An FR-GV-203 issue in FreeRADIUS 2.x before 2.2.10 allows "DHCP - Memory leak in decode_tlv()" and a denial of service.
CVE-2017-10978 3 Debian, Freeradius, Redhat 8 Debian Linux, Freeradius, Enterprise Linux Desktop and 5 more 2019-07-03 5.0 MEDIUM 7.5 HIGH
An FR-GV-201 issue in FreeRADIUS 2.x before 2.2.10 and 3.x before 3.0.15 allows "Read / write overflow in make_secret()" and a denial of service.
CVE-2019-11235 5 Canonical, Fedoraproject, Freeradius and 2 more 10 Ubuntu Linux, Fedora, Freeradius and 7 more 2019-05-13 7.5 HIGH 9.8 CRITICAL
FreeRADIUS before 3.0.19 mishandles the "each participant verifies that the received scalar is within a range, and that the received group element is a valid point on the curve being used" protection mechanism, aka a "Dragonblood" issue, a similar issue to CVE-2019-9498 and CVE-2019-9499.
CVE-2019-11234 4 Canonical, Fedoraproject, Freeradius and 1 more 4 Ubuntu Linux, Fedora, Freeradius and 1 more 2019-05-13 7.5 HIGH 9.8 CRITICAL
FreeRADIUS before 3.0.19 does not prevent use of reflection for authentication spoofing, aka a "Dragonblood" issue, a similar issue to CVE-2019-9497.
CVE-2001-1377 11 Freeradius, Gnu, Icradius and 8 more 11 Freeradius, Radius, Icradius and 8 more 2018-10-30 5.0 MEDIUM N/A
Multiple RADIUS implementations do not properly validate the Vendor-Length of the Vendor-Specific attribute, which allows remote attackers to cause a denial of service (crash) via a Vendor-Length that is less than 2.
CVE-2001-1376 12 Ascend, Freeradius, Gnu and 9 more 12 Radius, Freeradius, Radius and 9 more 2018-10-30 7.5 HIGH N/A
Buffer overflow in digest calculation function of multiple RADIUS implementations allows remote attackers to cause a denial of service and possibly execute arbitrary code via shared secret data.
