Radius Security Vulnerabilities - February

CVE-2001-1376

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.

CVE-2001-1377

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-2004-0131

The rad_print_request function in logger.c for GNU Radius daemon (radiusd) before 1.2 allows remote attackers to cause a denial of service (crash) via a UDP packet with an Acct-Status-Type attribute without a value and no Acct-Session-Id attribute, which causes a null dereference.

CVE-2004-0576

The radius daemon (radiusd) for GNU Radius 1.1, when compiled with the -enable-snmp option, allows remote attackers to cause a denial of service (server crash) via malformed SNMP messages containing an invalid OID.

CVE-2004-0849

Integer overflow in the asn_decode_string() function defined in asn1.c in radiusd for GNU Radius 1.1 and 1.2 before 1.2.94, when compiled with the --enable-snmp option, allows remote attackers to cause a denial of service (daemon crash) via certain SNMP requests.

CVE-2006-4181

Format string vulnerability in the sqllog function in the SQL accounting code for radiusd in GNU Radius 1.2 and 1.3 allows remote attackers to execute arbitrary code via unknown vectors.
