この更新では、apache2 HTTPD での以下のセキュリティ問題を修正します：

- LD_LIBRARY_PATH の不適切な処理。(CVE-2012-0883)

- ファイル名のエスケープの問題（CVE-2012-2687）さらに、RPM の変更ログに列挙されたいくつかの非セキュリティバグが修正されています。

Multiple vulnerabilities has been found and corrected in apache (ASF HTTPD) :

Insecure handling of LD_LIBRARY_PATH was found that could lead to the current working directory to be searched for DSOs. This could allow a local user to execute code as root if an administrator runs apachectl from an untrusted directory (CVE-2012-0883).

Possible XSS for sites which use mod_negotiation and allow untrusted uploads to locations which have MultiViews enabled (CVE-2012-2687).

The updated packages have been upgraded to the latest 2.2.23 version which is not vulnerable to these issues.

Update :

Packages for Mandriva Linux 2011 is also being provided.

The remote host is running a version of Mac OS X 10.8.x that is prior to 10.8.5. The newer version contains multiple security-related fixes for the following components :

  - Apache
  - Bind
  - Certificate Trust Policy
  - CoreGraphics
  - ImageIO
  - Installer
  - IPSec
  - Kernel
  - Mobile Device Management
  - OpenSSL
  - PHP
  - PostgreSQL
  - Power Management
  - QuickTime
  - Screen Lock
  - sudo

This update also addresses an issue in which certain Unicode strings could cause applications to unexpectedly quit.

Note that successful exploitation of the most serious issues could result in arbitrary code execution.

This Apache2 LTSS roll-up update for SUSE Linux Enterprise 10 SP3 LTSS fixes the following security issues and bugs :

  - CVE-2012-4557: Denial of Service via special requests in     mod_proxy_ajp

  - CVE-2012-0883: improper LD_LIBRARY_PATH handling

  - CVE-2012-2687: filename escaping problem

  - CVE-2012-0031: Fixed a scoreboard corruption (shared mem     segment) by child causes crash of privileged parent     (invalid free()) during shutdown.

  - CVE-2012-0053: Fixed an issue in error responses that     could expose 'httpOnly' cookies when no custom     ErrorDocument is specified for status code 400'.

  - The SSL configuration template has been adjusted not to     suggested weak ciphers CVE-2007-6750: The     'mod_reqtimeout' module was backported from Apache     2.2.21 to help mitigate the 'Slowloris' Denial of     Service attack.

    You need to enable the 'mod_reqtimeout' module in your     existing apache configuration to make it effective, e.g.
    in the APACHE_MODULES line in /etc/sysconfig/apache2.

  - CVE-2011-3639, CVE-2011-3368, CVE-2011-4317: This update     also includes several fixes for a mod_proxy reverse     exposure via RewriteRule or ProxyPassMatch directives.

  - CVE-2011-1473: Fixed the SSL renegotiation DoS by     disabling renegotiation by default.

  - CVE-2011-3607: Integer overflow in ap_pregsub function     resulting in a heap-based buffer overflow could     potentially allow local attackers to gain privileges

Additionally, some non-security bugs have been fixed which are listed in the changelog file.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its banner, the version of Apache 2.4.x running on the remote host is prior to 2.4.2. It is, therefore, potentially affected by an insecure library loading issue. 

The utility 'apachectl' can receive a zero-length directory name in the LD_LIBRARY_PATH via the 'envvars' file. A local attacker with access to that utility could exploit this to load a malicious Dynamic Shared Object (DSO), leading to arbitrary code execution. 

Note that Nessus did not actually test for this flaw, but instead has relied on the version in the server's banner.

Apache reports :

Insecure handling of LD_LIBRARY_PATH was found that could lead to the current working directory to be searched for DSOs. This could allow a local user to execute code as root if an administrator runs apachectl from an untrusted directory.

According to its banner, the version of Apache 2.2.x running on the remote host is prior to 2.2.23. It is, therefore, potentially affected by the following vulnerabilities :

  - The utility 'apachectl' can receive a zero-length     directory name in the LD_LIBRARY_PATH via the 'envvars'     file. A local attacker with access to that utility     could exploit this to load a malicious Dynamic Shared     Object (DSO), leading to arbitrary code execution.
    (CVE-2012-0883)

  - An input validation error exists related to     'mod_negotiation', 'Multiviews' and untrusted uploads     that can allow cross-site scripting attacks.
    (CVE-2012-2687)

Note that Nessus has not tested for these flaws but has instead relied on the version in the server's banner.

This update contains the 2.2.23 release of the Apache HTTP Server.

According to the web server's banner, the version of HP System Management Homepage (SMH) hosted on the remote web server is a version prior to 7.2.1.0. It is, therefore, affected by the following vulnerabilities :

  - An information disclosure vulnerability, known as BEAST,     exists in the SSL 3.0 and TLS 1.0 protocols due to a     flaw in the way the initialization vector (IV) is     selected when operating in cipher-block chaining (CBC)     modes. A man-in-the-middle attacker can exploit this     to obtain plaintext HTTP header data, by using a     blockwise chosen-boundary attack (BCBA) on an HTTPS     session, in conjunction with JavaScript code that uses     the HTML5 WebSocket API, the Java URLConnection API,     or the Silverlight WebClient API. (CVE-2011-3389)

  - The utility 'apachectl' can receive a zero-length     directory name in the LD_LIBRARY_PATH via the 'envvars'     file. A local attacker with access to that utility     could exploit this to load a malicious Dynamic Shared     Object (DSO), leading to arbitrary code execution.
    (CVE-2012-0883)

  - Numerous, unspecified errors could allow remote denial     of service attacks. (CVE-2012-2110, CVE-2012-2329,     CVE-2012-2336, CVE-2013-2357, CVE-2013-2358,     CVE-2013-2359, CVE-2013-2360)

  - The fix for CVE-2012-1823 does not completely correct     the CGI query parameter vulnerability. Disclosure of     PHP source code and code execution are still possible.
    Note that this vulnerability is exploitable only when     PHP is used in CGI-based configurations.  Apache with     'mod_php' is not an exploitable configuration.
    (CVE-2012-2311, CVE-2012-2335)

  - Unspecified errors exist that could allow unauthorized     access. (CVE-2012-5217, CVE-2013-2355)

  - Unspecified errors exist that could allow disclosure of     sensitive information. (CVE-2013-2356, CVE-2013-2363)

  - An unspecified error exists that could allow cross-site     scripting attacks. (CVE-2013-2361)

  - Unspecified errors exist that could allow a local     attacker to cause denial of service conditions.
    (CVE-2013-2362, CVE-2013-2364)

  - An as-yet unspecified vulnerability exists that could     cause a denial of service condition. (CVE-2013-4821)

The remote Solaris system is missing necessary patches to address security updates :

  - envvars (aka envvars-std) in the Apache HTTP Server     before 2.4.2 places a zero-length directory name in the     LD_LIBRARY_PATH, which allows local users to gain     privileges via a Trojan horse DSO in the current working     directory during execution of apachectl. (CVE-2012-0883)

  - Multiple cross-site scripting (XSS) vulnerabilities in     the make_variant_list function in mod_negotiation.c in     the mod_negotiation module in the Apache HTTP Server     2.4.x before 2.4.3, when the MultiViews option is     enabled, allow remote attackers to inject arbitrary web     script or HTML via a crafted filename that is not     properly handled during construction of a variant list.
    (CVE-2012-2687)

This update fixes the following security issues with apache2 httpd :

  - Improper LD_LIBRARY_PATH handling (CVE-2012-0883 )

  - Filename escaping problem (CVE-2012-2687 )

Additionally, some non-security bugs have been fixed as enumerated in the changelog of the RPM.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
