[原文]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.

[CNNVD]GNU Radius SNMP OID远程拒绝服务漏洞(CNNVD-200412-021)

        GNU Radius是一款开放源代码远程用户验证和审计服务器。
        GNU Radius处理部分畸形SNMP消息时存在问题,远程攻击者可以利用这个漏洞对Radius服务程序进行拒绝服务攻击。
        通过提包含一个非法OID如-1的畸形SNMP包,可导致GNU Radius服务程序崩溃。不过只有带 '-enable-snmp'编译的GNU Radius才存在此漏洞。

GNU Radius SNMP Invalid OID DoS
Remote / Network Access Denial of Service
Loss of Availability

- 漏洞描述

GNU Radius configured with --enable-snmp contains a flaw that may allow a denial of service. The issue is triggered when an SNMP transaction is initiated with an invalid Object ID parameter, and will result in loss of availability for the service.

- 解决方案

Upgrade to version 1.2 or higher, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by implementing the following workarounds: 1. reconfigure with "--disable-snmp" 2. block SNMP traffic (default port 161 UDP) on network interfaces which could provide undesirable traffic.
