Multiple buffer overflows in RADIUS daemon radiusd in (1) Merit 3.6b and (2) Lucent 2.1-2 RADIUS allow remote attackers to cause a denial of service or execute arbitrary commands.

Format string vulnerabilities in Livingston/Lucent RADIUS before 2.1.va.1 may allow local or remote attackers to cause a denial of service and possibly execute arbitrary code via format specifiers that are injected into log messages.

Directory traversal vulnerability in Livingston/Lucent RADIUS before 2.1.va.1 may allow attackers to read arbitrary files via a .. (dot dot) attack.

security flaw

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.

security flaw

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.
