FreeBSD : Multiple implementations -- DoS via hash algorithm collision (91be81e7-3fea-11e1-afc7-2c4138874f7d)

oCERT reports : A variety of programming languages suffer from a denial-of-service DoS condition against storage functions of key/value pairs in hash data structures, the condition can be leveraged by exploiting predictable collisions in the underlying hashing algorithms. The issue finds particul...

NTP Monitor List Scanner

This module identifies NTP servers which permit "monlist" queries and obtains the recent clients list. The monlist feature allows remote attackers to cause a denial of service traffic amplification via spoofed requests. The more clients there are in the list, the greater the amplification. This...

DNS Server Spoofed Request Amplification DDoS

The remote DNS server answers to any request. It is possible to query the name servers NS of the root zone '.' and get an answer that is bigger than the original request. By spoofing the source IP address, a remote attacker can leverage this 'amplification' to launch a denial of service attack...

Asterisk IAX2 FWDOWNL Request Spoofing Remote DoS

The firmware download protocol implemented in the version of Asterisk running on the remote host does not initiate a handshake. By spoofing an IAX2 FWDOWNL request, an unauthenticated, remote attacker may be able to leverage this issue to flood a third-party host with unwanted firmware packets fr...

Asterisk IAX2报文放大远程拒绝服务漏洞

BUGTRAQ ID: 28901 CVECAN ID: CVE-2008-1897 Asterisk是开放源码的软件PBX，支持各种VoIP协议和设备。 Asterisk在处理呼叫的机制上存在漏洞，远程攻击者可能利用此漏洞对第三方机器执行拒绝服务攻击。 IAX2协议允许ICNEW报文启动呼叫。ICNEW报文是18字节长的UDP报文，而呼叫可能非常长，包含有很多数据。由于UDP是可以伪造的，因此远程攻击者可以在IAX2握手期间欺骗IAX2握手，导致Asterisk服务器向目标发送大量数据，造成网络堵塞。 Asterisk Asterisk 1.4.x Asterisk Asterisk...
