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.

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.

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

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.

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.
