Security Enhancements and Fixes in PHP 5.2.12 :

- Fixed a safe_mode bypass in tempnam() identified by Grzegorz Stachowiak. (CVE-2009-3557, Rasmus)

- Fixed a open_basedir bypass in posix_mkfifo() identified by Grzegorz Stachowiak. (CVE-2009-3558, Rasmus)

- Added 'max_file_uploads' INI directive, which can be set to limit the number of file uploads per-request to 20 by default, to prevent possible DOS via temporary file exhaustion, identified by Bogdan Calin. (CVE-2009-4017, Ilia)

- Added protection for $_SESSION from interrupt corruption and improved 'session.save_path' check, identified by Stefan Esser.
(CVE-2009-4143, Stas)

- Fixed bug #49785 (insufficient input string validation of htmlspecialchars()). (CVE-2009-4142, Moriyoshi, hello at iwamot dot com)

According to its self-reported version number, the HP System Management Homepage install on the remote host is earlier than 6.2.
Such versions are reportedly affected by the following vulnerabilities :

  - Session renegotiations are not handled properly, which     could be exploited to insert arbitrary plaintext in a     man-in-the-middle attack. (CVE-2009-3555)

  - An attacker may be able to upload files using a POST     request with 'multipart/form-data' content even if the     target script doesn't actually support file uploads per     se. (CVE-2009-4017)

  - PHP's 'proc_open' function can be abused to bypass     'safe_mode_allowed_env_vars' and     'safe_mode_protected_env_vars' directives.
    (CVE-2009-4018)

  - PHP does not properly protect session data as relates     to interrupt corruption of '$_SESSION' and the     'session.save_path' directive. (CVE-2009-4143)

  - The application allows arbitrary URL redirections.
    (CVE-2010-1586 and CVE-2010-3283)

  - An information disclosure vulnerability exists in     Apache's mod_proxy_ajp, mod_reqtimeout, and     mod_proxy_http relating to timeout conditions. Note     that this issue only affects SMH on Windows.
    (CVE-2010-2068)

  - An as-yet unspecified information disclosure     vulnerability may allow an authorized user to gain     access to sensitive information, which in turn could     be leveraged to obtain root access on Linux installs     of SMH. (CVE-2010-3009)

  - There is an as-yet unspecified HTTP response splitting     issue. (CVE-2010-3011)

  - There is an as-yet unspecified cross-site scripting     issue. (CVE-2010-3012)

  - An as-yet unspecified vulnerability could lead to     remote disclosure of sensitive information.
    (CVE-2010-3284)

According to its banner, the version of PHP installed on the remote host is older than 5.2.12.  Such versions may be affected by several security issues :

  - It is possible to bypass the 'safe_mode' configuration     setting using 'tempnam()'. (CVE-2009-3557)

  - It is possible to bypass the 'open_basedir'     configuration setting using 'posix_mkfifo()'.     (CVE-2009-3558)

  - Provided file uploading is enabled (it is by default),     an attacker can upload files using a POST request with     'multipart/form-data' content even if the target script     doesn't actually support file uploads per se.  By     supplying a large number (15,000+) of files, an attacker     could cause the web server to stop responding while it     processes the file list. (CVE-2009-4017)

  - Missing protection for '$_SESSION' from interrupt     corruption and improved 'session.save_path' check.
    (CVE-2009-4143)

  - Insufficient input string validation in the     'htmlspecialchars()' function. (CVE-2009-4142)

The remote host is affected by the vulnerability described in GLSA-201001-03 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the     CVE identifiers referenced below and the associated PHP release notes     for details.
  Impact :

    A context-dependent attacker could execute arbitrary code via a     specially crafted string containing an HTML entity when the mbstring     extension is enabled. Furthermore a remote attacker could execute     arbitrary code via a specially crafted GD graphics file.
    A remote attacker could also cause a Denial of Service via a malformed     string passed to the json_decode() function, via a specially crafted     ZIP file passed to the php_zip_make_relative_path() function, via a     malformed JPEG image passed to the exif_read_data() function, or via     temporary file exhaustion. It is also possible for an attacker to spoof     certificates, bypass various safe_mode and open_basedir restrictions     when certain criteria are met, perform Cross-site scripting attacks,     more easily perform SQL injection attacks, manipulate settings of other     virtual hosts on the same server via a malicious .htaccess entry when     running on Apache, disclose memory portions, and write arbitrary files     via a specially crafted ZIP archive. Some vulnerabilities with unknown     impact and attack vectors have been reported as well.
  Workaround :

    There is no known workaround at this time.

Maksymilian Arciemowicz discovered that PHP did not properly handle the ini_restore function. An attacker could exploit this issue to obtain random memory contents or to cause the PHP server to crash, resulting in a denial of service. (CVE-2009-2626)

It was discovered that the htmlspecialchars function did not properly handle certain character sequences, which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data (such as passwords), within the same domain.
(CVE-2009-4142)

Stefan Esser discovered that PHP did not properly handle session data.
An attacker could exploit this issue to bypass safe_mode or open_basedir restrictions. (CVE-2009-4143).

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

Several remote vulnerabilities have been discovered in PHP 5, an hypertext preprocessor. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-4142     The htmlspecialchars function does not properly handle     invalid multi-byte sequences.

  - CVE-2009-4143     Memory corruption via session interruption.

In the stable distribution (lenny), this update also includes bug fixes (bug #529278, #556459, #565387, #523073) that were to be included in a stable point release as version 5.2.6.dfsg.1-1+lenny5.

According to its banner, the version of PHP 5.2.x installed on the remote host is earlier than 5.2.12.  Such versions are potentially affected by multiple vulnerabilities : 

  - A safe_mode bypass in tempnam(). (CVE-2009-3557)

  - An open_basedir bypass in posix_mkfifo(). (CVE-2009-3558)

  - A possible denial-of-service via temporary file exhaustion caused by a failure to limit the number of file uploads per request. (CVE-2009-4017)

  - An arbitrary code execution vulnerability in the 'session.save_path()' function and the '$_SESSION' data structure. (CVE-2009-4143)

  - A cross-site scripting vulnerability becuase the 'htmlspecialcharacters()' function fails to properly handle some malformed multibyte character sequences.

The remote host is running HP System Management Homepage (HPSMH), a web-based interface for managing individual ProLiant and Integrity servers.

Versions of HP System Management Homepage earlier than 6.2 are potentially affected by the following vulnerabilities :

  - Session renegotiations are not handled properly, which could be exploited to insert arbitrary plaintext in a man-in-the-middle attack. (CVE-2009-3555)

  - An attacker may be able to upload files using a POST request with 'multipart/form-data' content even if the target script doesn't actually support file uploads per se. (CVE-2009-4017)
