Bind 9 竞争条件远程拒绝服务漏洞

CVE ID: CVE-2011-0414 BIND是一款开放源码的DNS服务器软件，由美国加州大学Berkeley分校开发和维护的，BIND 9在2000年十月份推出。 BIND9在进行请求的处理时存在竞争条件问题，远程攻击者可利用此漏洞导致进程发生死锁导致拒绝服务的情况。 当Bind被配置为权威服务器时，如果进程在处理查询请求的同时执行DDNS更新和增量区传输（IXFR），则会发生竞争条件导致的死锁。 另外，Bind在处理缓存解析器记录的新DNSSEC DS记录时存在问题，可导致名字解析失败。没有使用DNSSEC验证的配置不受此漏洞影响。 Debian bind9 厂商补丁：...

ISC BIND 9 RRSIG记录类型远程拒绝服务漏洞

BUGTRAQ ID: 41730 CVE ID: CVE-2010-0213 BIND是一个应用非常广泛的DNS协议的实现，由ISC负责维护，具体的开发由Nominum公司完成。 如果用户向运行BIND的验证递归服务器提交了RRSIG类型记录的查询请求，且服务器静态的或通过DLV配置了一个或多个信任锚，则在缓存中不存在应答的情况下，服务器就会陷入为包含有所查询名称区域的权威服务器反复生成RRSIG查询的循环。在正常操作中很少会出现这种情况，因为在启用了DNSSEC 且存在记录的情况下，RRSIG已经包含在了对所涵盖RR类型查询的响应中。 ISC BIND 9.7.1-P1 ISC BI...
