Multiple format string vulnerabilities in Yet Another Radius Daemon (YARD RADIUS) 1.1.2 allow context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via format string specifiers in a request in the (1) logmsg function in log.c or (2) version or (3) buildversion function in version.c.

Buffer overflow in the processmenu function in yardradius 1.0.20 allows remote attackers to execute arbitrary code.

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.
