This update has been rated as having important security impact by the Red Hat Security Response Team. The Apache HTTP Server is a popular Web server. A denial of service flaw was found in the Apache mod_proxy module when it was used as a reverse proxy. A remote attacker could use this flaw to force a proxy process to consume large amounts of CPU time. (CVE-2009-1890) A denial of service flaw was found in the Apache mod_deflate module.

This would cause mod_deflate to consume large amounts of CPU if mod_deflate was enabled for a large file.

After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

    available for Red Hat Enterprise Linux 4.
    
    This update has been rated as having moderate security impact by the
    Red Hat Security Response Team.
    
    The Apache HTTP Server is a popular Web server.
    
    A flaw was found in the way the TLS/SSL (Transport Layer
    Security/Secure Sockets Layer) protocols handle session renegotiation.
    A man-in-the-middle attacker could use this flaw to prefix arbitrary
    plain text to a client's session (for example, an HTTPS connection to
    a website). This could force the server to process an attacker's
    request as if authenticated using the victim's credentials. This
    update partially mitigates this flaw for SSL sessions to HTTP servers
    using mod_ssl by rejecting client-requested renegotiation.
    (CVE-2009-3555)
    
    Note: This update does not fully resolve the issue for HTTPS servers.
    An attack is still possible in configurations that require a
    server-initiated renegotiation. Refer to the following Knowledgebase
    article for further information:
    http://kbase.redhat.com/faq/docs/DOC-20491
    
    A denial of service flaw was found in the Apache mod_deflate module.
    This module continued to compress large files until compression was
    complete, even if the network connection that requested the content
    was closed before compression completed. This would cause mod_deflate
    to consume large amounts of CPU if mod_deflate was enabled for a large
    file. (CVE-2009-1891)
    
    A NULL pointer dereference flaw was found in the Apache mod_proxy_ftp
    module. A malicious FTP server to which requests are being proxied
    could use this flaw to crash an httpd child process via a malformed
    reply to the EPSV or PASV commands, resulting in a limited denial of
    service. (CVE-2009-3094)
    
    A second flaw was found in the Apache mod_proxy_ftp module. In a
    reverse proxy configuration, a remote attacker could use this flaw to
    bypass intended access restrictions by creating a carefully-crafted
    HTTP Authorization header, allowing the attacker to send arbitrary
    commands to the FTP server. (CVE-2009-3095)
    
    All httpd users should upgrade to these updated packages, which
    contain backported patches to correct these issues. After installing
    the updated packages, the httpd daemon must be restarted for the
    update to take effect."

    descriptionFrom Red Hat Security Advisory 2009:1205 : Updated httpd packages that fix multiple security issues and a bug are now available for Red Hat Enterprise Linux 3. This update has been rated as having moderate security impact by the Red Hat Security Response Team. The Apache HTTP Server is a popular Web server. The httpd package shipped with Red Hat Enterprise Linux 3 contains embedded copies of the Apache Portable Runtime (APR) libraries, which provide a free library of C data structures and routines, and also additional utility interfaces to support XML parsing, LDAP, database interfaces, URI parsing, and more. Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way the Apache Portable Runtime (APR) manages memory pool and relocatable memory allocations. An attacker could use these flaws to issue a specially crafted request for memory allocation, which would lead to a denial of service (application crash) or, potentially, execute arbitrary code with the privileges of an application using the APR libraries. (CVE-2009-2412) A denial of service flaw was found in the Apache mod_deflate module. This module continued to compress large files until compression was complete, even if the network connection that requested the content was closed before compression completed. This would cause mod_deflate to consume large amounts of CPU if mod_deflate was enabled for a large file. (CVE-2009-1891) This update also fixes the following bug : * in some cases the Content-Length header was dropped from HEAD responses. This resulted in certain sites not working correctly with mod_proxy, such as www.windowsupdate.com. (BZ#506016) All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

    remote host is prior to 2.2.12. It is, therefore, affected by the
    following vulnerabilities :
    
      - A heap-based buffer underwrite flaw exists in the
        function 'apr_strmatch_precompile()' in the bundled copy
        of the APR-util library, which could be triggered when
        parsing configuration data to crash the daemon.
        (CVE-2009-0023)
    
      - A flaw in the mod_proxy_ajp module in version 2.2.11
        only may allow a remote attacker to obtain sensitive
        response data intended for a client that sent an
        earlier POST request with no request body.
        (CVE-2009-1191)
    
      - The server does not limit the use of directives in a
        .htaccess file as expected based on directives such
        as 'AllowOverride' and 'Options' in the configuration
        file, which could enable a local user to bypass
        security restrictions. (CVE-2009-1195)
    
      - Failure to properly handle an amount of streamed data
        that exceeds the Content-Length value allows a remote
        attacker to force a proxy process to consume CPU time
        indefinitely when mod_proxy is used in a reverse proxy
        configuration. (CVE-2009-1890)
    
      - Failure of mod_deflate to stop compressing a file when
        the associated network connection is closed may allow a
        remote attacker to consume large amounts of CPU if
        there is a large (>10 MB) file available that has
        mod_deflate enabled. (CVE-2009-1891)
    
      - Using a specially crafted XML document with a large
        number of nested entities, a remote attacker may be
        able to consume an excessive amount of memory due to
        a flaw in the bundled expat XML parser used by the
        mod_dav and mod_dav_svn modules. (CVE-2009-1955)
    
      - There is an off-by-one overflow in the function
        'apr_brigade_vprintf()' in the bundled copy of the
        APR-util library in the way it handles a variable list
        of arguments, which could be leveraged on big-endian
        platforms to perform information disclosure or denial
        of service attacks. (CVE-2009-1956)

    "From Red Hat Security Advisory 2009:1580 :
    
    Updated httpd packages that fix multiple security issues are now
    available for Red Hat Enterprise Linux 4.
    
    This update has been rated as having moderate security impact by the
    Red Hat Security Response Team.
    
    The Apache HTTP Server is a popular Web server.
    
    A flaw was found in the way the TLS/SSL (Transport Layer
    Security/Secure Sockets Layer) protocols handle session renegotiation.
    A man-in-the-middle attacker could use this flaw to prefix arbitrary
    plain text to a client's session (for example, an HTTPS connection to
    a website). This could force the server to process an attacker's
    request as if authenticated using the victim's credentials. This
    update partially mitigates this flaw for SSL sessions to HTTP servers
    using mod_ssl by rejecting client-requested renegotiation.
    (CVE-2009-3555)
    
    Note: This update does not fully resolve the issue for HTTPS servers.
    An attack is still possible in configurations that require a
    server-initiated renegotiation. Refer to the following Knowledgebase
    article for further information:
    http://kbase.redhat.com/faq/docs/DOC-20491
    
    A denial of service flaw was found in the Apache mod_deflate module.
    This module continued to compress large files until compression was
    complete, even if the network connection that requested the content
    was closed before compression completed. This would cause mod_deflate
    to consume large amounts of CPU if mod_deflate was enabled for a large
    file. (CVE-2009-1891)
    
    A NULL pointer dereference flaw was found in the Apache mod_proxy_ftp
    module. A malicious FTP server to which requests are being proxied
    could use this flaw to crash an httpd child process via a malformed
    reply to the EPSV or PASV commands, resulting in a limited denial of
    service. (CVE-2009-3094)
    
    A second flaw was found in the Apache mod_proxy_ftp module. In a
    reverse proxy configuration, a remote attacker could use this flaw to
    bypass intended access restrictions by creating a carefully-crafted
    HTTP Authorization header, allowing the attacker to send arbitrary
    commands to the FTP server. (CVE-2009-3095)
    
    All httpd users should upgrade to these updated packages, which
    contain backported patches to correct these issues. After installing
    the updated packages, the httpd daemon must be restarted for the
    update to take effect."

    descriptionUpdated httpd packages that fix multiple security issues and a bug are now available for Red Hat Enterprise Linux 3. This update has been rated as having moderate security impact by the Red Hat Security Response Team. The Apache HTTP Server is a popular Web server. The httpd package shipped with Red Hat Enterprise Linux 3 contains embedded copies of the Apache Portable Runtime (APR) libraries, which provide a free library of C data structures and routines, and also additional utility interfaces to support XML parsing, LDAP, database interfaces, URI parsing, and more. Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way the Apache Portable Runtime (APR) manages memory pool and relocatable memory allocations. An attacker could use these flaws to issue a specially crafted request for memory allocation, which would lead to a denial of service (application crash) or, potentially, execute arbitrary code with the privileges of an application using the APR libraries. (CVE-2009-2412) A denial of service flaw was found in the Apache mod_deflate module. This module continued to compress large files until compression was complete, even if the network connection that requested the content was closed before compression completed. This would cause mod_deflate to consume large amounts of CPU if mod_deflate was enabled for a large file. (CVE-2009-1891) This update also fixes the following bug : * in some cases the Content-Length header was dropped from HEAD responses. This resulted in certain sites not working correctly with mod_proxy, such as www.windowsupdate.com. (BZ#506016) All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

    Authorization HTTP header
    
    CVE-2009-3555 TLS: MITM attacks via session renegotiation
    
    A flaw was found in the way the TLS/SSL (Transport Layer
    Security/Secure Sockets Layer) protocols handle session renegotiation.
    A man-in-the-middle attacker could use this flaw to prefix arbitrary
    plain text to a client's session (for example, an HTTPS connection to
    a website). This could force the server to process an attacker's
    request as if authenticated using the victim's credentials. This
    update partially mitigates this flaw for SSL sessions to HTTP servers
    using mod_ssl by rejecting client-requested renegotiation.
    (CVE-2009-3555)
    
    Note: This update does not fully resolve the issue for HTTPS servers.
    An attack is still possible in configurations that require a
    server-initiated renegotiation. Refer to the following Knowledgebase
    article for further information:
    http://kbase.redhat.com/faq/docs/DOC-20491
    
    A denial of service flaw was found in the Apache mod_deflate module.
    This module continued to compress large files until compression was
    complete, even if the network connection that requested the content
    was closed before compression completed. This would cause mod_deflate
    to consume large amounts of CPU if mod_deflate was enabled for a large
    file. (CVE-2009-1891) - SL4 only
    
    A NULL pointer dereference flaw was found in the Apache mod_proxy_ftp
    module. A malicious FTP server to which requests are being proxied
    could use this flaw to crash an httpd child process via a malformed
    reply to the EPSV or PASV commands, resulting in a limited denial of
    service. (CVE-2009-3094)
    
    A second flaw was found in the Apache mod_proxy_ftp module. In a
    reverse proxy configuration, a remote attacker could use this flaw to
    bypass intended access restrictions by creating a carefully-crafted
    HTTP Authorization header, allowing the attacker to send arbitrary
    commands to the FTP server. (CVE-2009-3095)
    
    After installing the updated packages, the httpd daemon must be
    restarted for the update to take effect."

    descriptionMultiple vulnerabilities has been found and corrected in apache : The stream_reqbody_cl function in mod_proxy_http.c in the mod_proxy module in the Apache HTTP Server before 2.3.3, when a reverse proxy is configured, does not properly handle an amount of streamed data that exceeds the Content-Length value, which allows remote attackers to cause a denial of service (CPU consumption) via crafted requests (CVE-2009-1890). Fix a potential Denial-of-Service attack against mod_deflate or other modules, by forcing the server to consume CPU time in compressing a large file after a client disconnects (CVE-2009-1891). This update provides fixes for these vulnerabilities.

    descriptionMultiple vulnerabilities has been found and corrected in apache : Memory leak in the zlib_stateful_init function in crypto/comp/c_zlib.c in libssl in OpenSSL 0.9.8f through 0.9.8h allows remote attackers to cause a denial of service (memory consumption) via multiple calls, as demonstrated by initial SSL client handshakes to the Apache HTTP Server mod_ssl that specify a compression algorithm (CVE-2008-1678). Note that this security issue does not really apply as zlib compression is not enabled in the openssl build provided by Mandriva, but apache is patched to address this issue anyway (conserns 2008.1 only). mod_proxy_ajp.c in the mod_proxy_ajp module in the Apache HTTP Server 2.2.11 allows remote attackers to obtain sensitive response data, intended for a client that sent an earlier POST request with no request body, via an HTTP request (CVE-2009-1191). Cross-site scripting (XSS) vulnerability in proxy_ftp.c in the mod_proxy_ftp module in Apache 2.0.63 and earlier, and mod_proxy_ftp.c in the mod_proxy_ftp module in Apache 2.2.9 and earlier 2.2 versions, allows remote attackers to inject arbitrary web script or HTML via wildcards in a pathname in an FTP URI (CVE-2008-2939). Note that this security issue was initially addressed with MDVSA-2008:195 but the patch fixing the issue was added but not applied in 2009.0. The Apache HTTP Server 2.2.11 and earlier 2.2 versions does not properly handle Options=IncludesNOEXEC in the AllowOverride directive, which allows local users to gain privileges by configuring (1) Options Includes, (2) Options +Includes, or (3) Options +IncludesNOEXEC in a .htaccess file, and then inserting an exec element in a .shtml file (CVE-2009-1195). The stream_reqbody_cl function in mod_proxy_http.c in the mod_proxy module in the Apache HTTP Server before 2.3.3, when a reverse proxy is configured, does not properly handle an amount of streamed data that exceeds the Content-Length value, which allows remote attackers to cause a denial of service (CPU consumption) via crafted requests (CVE-2009-1890). Fix a potential Denial-of-Service attack against mod_deflate or other modules, by forcing the server to consume CPU time in compressing a large file after a client disconnects (CVE-2009-1891). The ap_proxy_ftp_handler function in modules/proxy/proxy_ftp.c in the mod_proxy_ftp module in the Apache HTTP Server 2.0.63 and 2.2.13 allows remote FTP servers to cause a denial of service (NULL pointer dereference and child process crash) via a malformed reply to an EPSV command (CVE-2009-3094). The mod_proxy_ftp module in the Apache HTTP Server allows remote attackers to bypass intended access restrictions and send arbitrary commands to an FTP server via vectors related to the embedding of these commands in the Authorization HTTP header, as demonstrated by a certain module in VulnDisco Pack Professional 8.11. NOTE: as of 20090903, this disclosure has no actionable information. However, because the VulnDisco Pack author is a reliable researcher, the issue is being assigned a CVE identifier for tracking purposes (CVE-2009-3095). Apache is affected by SSL injection or man-in-the-middle attacks due to a design flaw in the SSL and/or TLS protocols. A short term solution was released Sat Nov 07 2009 by the ASF team to mitigate these problems. Apache will now reject in-session renegotiation (CVE-2009-3555). Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers This update provides a solution to these vulnerabilities.

    descriptionThis update of the Apache webserver fixes various security issues : - the option IncludesNOEXEC could be bypassed via .htaccess. (CVE-2009-1195) - mod_proxy could run into an infinite loop when used as reverse proxy. (CVE-2009-1890) - mod_deflate continued to compress large files even after a network connection was closed, causing mod_deflate to consume large amounts of CPU. (CVE-2009-1891) - The ap_proxy_ftp_handler function in modules/proxy/proxy_ftp.c in the mod_proxy_ftp module allows remote FTP servers to cause a denial of service (NULL pointer dereference and child process crash) via a malformed reply to an EPSV command. (CVE-2009-3094) - access restriction bypass in mod_proxy_ftp module. (CVE-2009-3095) Also a incompatibility between mod_cache and mod_rewrite was fixed.

descriptionBugraq ID: 35623 CVE ID:CVE-2009-1891 Apache是一款流行HTTP服务程序。 Apache mod_deflat模块不正确处理特殊请求,远程攻击者可以利用漏洞使服务程序崩溃。 当mod_deflate启用时下载一个文件,在结束之前中止连接,会使CPU压缩文件达到100%利用率。 即使一个不太大的文件(几MB),通过在这个文件中提交同步请求并马上中止连接,由于这个文件在平行过程中多次压缩,可导致消耗大量CPU时间而造成拒绝服务攻击。 Apache Software Foundation Apache 2.2.11 Apache Software Foundation Apache 2.2.10 Apache Software Foundation Apache 2.2.9 Apache Software Foundation Apache 2.2.8 Apache Software Foundation Apache 2.2.6 Apache Software Foundation Apache 2.2.5 Apache Software Foundation Apache 2.2.4 Apache Software Foundation Apache 2.2.3 Apache Software Foundation Apache 2.2.2 Apache Software Foundation Apache 2.2.7-dev Apache Software Foundation Apache 2.2.6-dev Apache Software Foundation Apache 2.2.5-dev Apache Software Foundation Apache 2.2.1 Apache Software Foundation Apache 2.2 用户可参考如下链接获得补丁信息: http://svn.apache.org/viewvc?view=rev&amp;revision=791454
