详细描述
Half-Life ClanMod插件用于"半条命"游戏服务器。

问题存在于'cm_log'命令中，设计用于写消息到服务日志文件中。问题代码server.cpp如下：

2790 void CmdLogMessage()
2791 {
2792         if (CMD_ARGC() > 1) {
2793               UTIL_FillText((char*)CMD_ARGS()/*UTIL_GetVarArgs(1,FALSE)*/, NULL, 256,cmSet.allow_to_execute,NULL,
NULL,TRUE);
2794               UTIL_LogPrintf(UTIL_VarArgs("[%s] %s",Plugin_info.logtag,com_token));
2795         }
2796         else
2797               PrintErrorInfo("cm_log");
2798
2799         //Close any opened gate
2800         cmSet.allow_to_execute_time = gpGlobals->time + 0.25;
2801 }

2794行UTIL_LogPrintf在接收用户提供的字符串时缺少正确检查，可发生格式字符串问题。

不知它们的OP知了会怎样了。。。
