Tomcat 又爆安全漏洞，情何以堪

CVE-2011-1184 Apache Tomcat - Multiple weaknesses in HTTP DIGEST authentication

严重性: 中等

所影响的版本：
- - Tomcat 7.0.0 to 7.0.11
- - Tomcat 6.0.0 to 6.0.32
- - Tomcat 5.5.0 to 5.5.33
- - Earlier, unsupported versions may also be affected

漏洞描述:
The implementation of HTTP DIGEST authentication was discovered to
have several weaknesses:
- - replay attacks were permitted
- - server nonces were not checked
- - client nonce counts were not checked
- - qop values were not checked
- - realm values were not checked
- - the server secret was hard-coded to a known string
The result of these weaknesses is that DIGEST authentication was only
as secure as BASIC authentication.

解决方法:
Users of Tomcat 7.0.x should upgrade to 7.0.12 or later
Users of Tomcat 6.0.x should upgrade to 6.0.33 or later
Users of Tomcat 5.5.x should upgrade to 5.5.34 or later
