Description:
A vulnerability has been reported in GNU Radius, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an input validation error within the "asn_decode_string()" function. This can be exploited to cause an integer overflow and thereby crash the radius daemon by sending a specially crafted SNMP datagram to a vulnerable system.
Successful exploitation requires that radiusd has been compiled with the "--enable-snmp" option (not default setting).
The vulnerability has been reported in versions 1.1 and 1.2.
