如何将安全更新应用到apache

我一直在对我们的networking服务器进行一些渗透testing，并且提出了一些问题。 其中之一就是apache需要安全更新（ http://www.ubuntu.com/usn/usn-1765-1/ ）。

我正在运行的Ubuntu 12.04 LTS和该页面上的说明build议运行

apt-get更新

其次是

• Apache 2.4 + PHP-FPM + mod_fastcgi（设置PHP-FPM的问题）
• 将站点从一台服务器切换到另一台服务器而不更改DNS
• 工人MPM或Prefork？
• 创build新的站点configuration时重新启动Apache
• .htaccess errordocument禁用标题

apt-get升级

将解决这个问题，不幸的是我被告知有没有更新的软件包。 我试图从链接下载tarball，但现在我已经解压，我不知道该怎么办。

search谷歌似乎轰炸如何安装Apache的指令，但如果有人知道一个指导，将是伟大的。 任何build议不胜感激。

apt-cache策略的输出apache2：

这里是突出问题的渗透testing的内容：

  Apache Partial HTTP Request Denial of Service Vulnerability - Zero Day QID: 86847 Category: Web server CVE ID: - Vendor Reference - Bugtraq ID: - Service Modified: 05/30/2013 User Modified: - Edited: No PCI Vuln: No THREAT: The Apache HTTP Server, commonly referred to as Apache is a freely available Web server. Apache is vulnerable to a denial of service due to holding a connection open for partial HTTP requests. Apache Versions 1.x and 2.x are vulnerable. IMPACT: A remote attacker can cause a denial of service against the Web server which would prevent legitimate users from accessing the site. Denial of service tools and scripts such as Slowloris takes advantage of this vulnerability. SOLUTION: Patch - There are no vendor-supplied patches available at this time. Workaround: - Reverse proxies, load balancers and iptables can help to prevent this attack from occurring. - Adjusting the TimeOut Directive can also prevent this attack from occurring. - A new module mod_reqtimeout has been introduced since Apache 2.2.15 to provide tools for mitigation against these forms of attack. Also refer to Cert Blog and Slowloris and Mitigations for Apache document for further information. COMPLIANCE: Not Applicable EXPLOITABILITY: There is no exploitability information for this vulnerability. ASSOCIATED MALWARE: There is no malware information for this vulnerability. RESULTS: QID: 86847 detected on port 80 over TCP - Apache/2.2.22 (Ubuntu) 3 Apache HTTP Server Prior to 2.2.23 Multiple Vulnerabilities QID: 87133 Category: Web server CVE ID: CVE-2012-2687 CVE-2012-0883 Vendor Reference Apache Bugtraq ID: 53046, 55131 Service Modified: 01/02/2013 User Modified: - Edited: No PCI Vuln: Yes THREAT: Apache HTTP Server is an HTTP web server application. Apache server prior to version 2.2.23 is affected by multiple issues: Insecure LD_LIBRARY_PATH handling Cross-site scripting in mod_negotiation when untrusted uploads are supported Affected Versions: Apache HTTP Server prior to version 2.2.23 IMPACT: Successful exploitation may lead to execution of arbitrary code on the system within the context of the affected applications. SOLUTION: These vulnerabilities have been patched in Apache 2.2.23. Refer to Apache httpd 2.2 Security Vulnerabilities. Patch: Following are links for downloading patches to fix the vulnerabilities: Apache 2.2.23 (Apache HTTP Server) COMPLIANCE: Not Applicable EXPLOITABILITY: There is no exploitability information for this vulnerability. ASSOCIATED MALWARE: There is no malware information for this vulnerability. RESULTS: QID 87133 detected on port 80 - Apache/2.2.22 (Ubuntu) 3 Apache Prior to 2.4.4 and 2.2.24 Multiple Vulnerabilities port 80/tcp QID: 87156 Category: Web server CVE ID: CVE-2012-3499 CVE-2012-4558 Vendor Reference Apache httpd 2.2 Vulnerabilities, Apache httpd 2.4 Vulnerabilities Bugtraq ID: 58165 Service Modified: 05/22/2013 User Modified: - Edited: No PCI Vuln: Yes THREAT: Apache HTTP Server is an HTTP web server application. Apache HTTP Server is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input. - Various XSS flaws exist due to unescaped hostnames and URIs HTML output in mod_info, mod_status, mod_imagemap, mod_ldap, and mod_proxy_ftp. - A XSS flaw affects the mod_proxy_balancer manager interface. Affected Versions: Apache HTTP Server prior to 2.4.4 Apache HTTP Server prior to 2.2.24 IMPACT: An attacker may leverage these issues to execute arbitrary HTML and script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker launch additional attacks. SOLUTION: These vulnerabilities have been patched in Apache 2.2.24 and 2.4.4. Refer to Apache httpd 2.4.4 Changelog and Apache httpd 2.2.24 Changelog. Ubuntu users refer to Ubuntu advisory USN-1765-1 for affected packages and patching details, or update with your package manager. Patch: Following are links for downloading patches to fix the vulnerabilities: Apache 2.2.24 (Apache HTTP Server 2.2.24) Apache 2.4.4 (Apache HTTP Server 2.4.4) COMPLIANCE: Not Applicable EXPLOITABILITY: There is no exploitability information for this vulnerability. ASSOCIATED MALWARE: There is no malware information for this vulnerability. RESULTS: QID 87156 detected on port 80 - Apache/2.2.22 (Ubuntu) 3 Apache HTTP Server Prior to 2.2.25 Multiple Vulnerabilities port 80/tcp QID: 87233 Category: Web server CVE ID: CVE-2013-1896 CVE-2013-1862 Vendor Reference Apache 2.2.25 Bugtraq ID: - Service Modified: 07/15/2013 User Modified: - Edited: No PCI Vuln: Yes THREAT: Apache HTTP Server is an HTTP web server application. Apache HTTP Server versons before to 2.2.25 are exposed to following vulnerabilities: mod_rewrite.c in the mod_rewrite module in the Apache HTTP Server 2.2.x before 2.2.25 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to execute arbitrary commands via an HTTP request containing an escape sequence for a terminal emulator (CVE-2013-1862). mod_dav.c in the Apache HTTP Server versions before 2.2.25 do not properly determine whether DAV is enabled for a URI, which allows remote attackers to cause a denial of service (segmentation fault) via a MERGE request in which the URI is configured for handling by the mod_dav_svn module, but a certain href attribute in XML data refers to a non-DAV URI (CVE-2013-1896). IMPACT: Successfully exploiting these vulnerabilities might allow a remote attacker to execute code or cause denial of service. SOLUTION: These vulnerabilities have been patched in Apache 2.2.25. Refer to Apache httpd 2.2.25 Changelog. Patch: Following are links for downloading patches to fix the vulnerabilities: Apache 2.2.25 COMPLIANCE: Not Applicable EXPLOITABILITY: There is no exploitability information for this vulnerability. ASSOCIATED MALWARE: There is no malware information for this vulnerability. RESULTS: QID 87233 detected on port 80 - Apache/2.2.22 (Ubuntu)
