Multiple vulnerabilities was discovered and corrected in php :

The dba_replace function in PHP 5.2.6 and 4.x allows context-dependent attackers to cause a denial of service (file truncation) via a key with the NULL byte. NOTE: this might only be a vulnerability in limited circumstances in which the attacker can modify or add database entries but does not have permissions to truncate the file (CVE-2008-7068).

The JSON_parser function (ext/json/JSON_parser.c) in PHP 5.2.x before 5.2.9 allows remote attackers to cause a denial of service (segmentation fault) via a malformed string to the json_decode API function (CVE-2009-1271).

  - Fixed upstream bug #48378 (exif_read_data() segfaults on     certain corrupted .jpeg files) (CVE-2009-2687).

The php_openssl_apply_verification_policy function in PHP before 5.2.11 does not properly perform certificate validation, which has unknown impact and attack vectors, probably related to an ability to spoof certificates (CVE-2009-3291).

Unspecified vulnerability in PHP before 5.2.11 has unknown impact and attack vectors related to missing sanity checks around exif processing. (CVE-2009-3292)

Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect sanity check for the color index. (CVE-2009-3293)

The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.0, and the GD Graphics Library 2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability than CVE-2009-3293. NOTE: some of these details are obtained from third-party information (CVE-2009-3546).

The tempnam function in ext/standard/file.c in PHP 5.2.11 and earlier, and 5.3.x before 5.3.1, allows context-dependent attackers to bypass safe_mode restrictions, and create files in group-writable or world-writable directories, via the dir and prefix arguments (CVE-2009-3557).

The posix_mkfifo function in ext/posix/posix.c in PHP 5.2.11 and earlier, and 5.3.x before 5.3.1, allows context-dependent attackers to bypass open_basedir restrictions, and create FIFO files, via the pathname and mode arguments, as demonstrated by creating a .htaccess file (CVE-2009-3558).

PHP 5.2.11, and 5.3.x before 5.3.1, does not restrict the number of temporary files created when handling a multipart/form-data POST request, which allows remote attackers to cause a denial of service (resource exhaustion), and makes it easier for remote attackers to exploit local file inclusion vulnerabilities, via multiple requests, related to lack of support for the max_file_uploads directive (CVE-2009-4017).

The proc_open function in ext/standard/proc_open.c in PHP before 5.2.11 and 5.3.x before 5.3.1 does not enforce the (1) safe_mode_allowed_env_vars and (2) safe_mode_protected_env_vars directives, which allows context-dependent attackers to execute programs with an arbitrary environment via the env parameter, as demonstrated by a crafted value of the LD_LIBRARY_PATH environment variable (CVE-2009-4018).

The dba_replace function in PHP 5.2.6 and 4.x allows context-dependent attackers to cause a denial of service (file truncation) via a key with the NULL byte. NOTE: this might only be a vulnerability in limited circumstances in which the attacker can modify or add database entries but does not have permissions to truncate the file (CVE-2008-7068).

The php_openssl_apply_verification_policy function in PHP before 5.2.11 does not properly perform certificate validation, which has unknown impact and attack vectors, probably related to an ability to spoof certificates (CVE-2009-3291).

Unspecified vulnerability in PHP before 5.2.11 has unknown impact and attack vectors related to missing sanity checks around exif processing. (CVE-2009-3292)

Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect sanity check for the color index. (CVE-2009-3293). However in Mandriva we don't use the bundled libgd source in php per default, there is a unsupported package in contrib named php-gd-bundled that eventually will get updated to pickup these fixes.

The php-suhosin package has been upgraded to 0.9.22 which has better support for apache vhosts.

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers

This update provides a solution to these vulnerabilities.

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.

This update fixes the JSON parser (CVE-2009-1271) and the zip packer code (CVE-2009-1272) in php5. Both bugs can lead to a remote denial of service attack.

A vulnerability has been found and corrected in PHP :

The JSON_parser function (ext/json/JSON_parser.c) in PHP 5.2.x before 5.2.9 allows remote attackers to cause a denial of service (segmentation fault) via a malformed string to the json_decode API function (CVE-2009-1271).

The updated packages have been patched to correct these issues.

USN-761-1 fixed vulnerabilities in PHP. This update provides the corresponding updates for Ubuntu 9.04.

It was discovered that PHP did not sanitize certain error messages when display_errors is enabled, 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-2008-5814)

It was discovered that PHP did not properly handle certain malformed strings when being parsed by the json_decode function. A remote attacker could exploit this flaw and cause the PHP server to crash, resulting in a denial of service. This issue only affected Ubuntu 8.04 and 8.10.
(CVE-2009-1271).

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.

Update to PHP 5.2.9 A heap-based buffer overflow flaw was found in PHP's mbstring extension. A remote attacker able to pass arbitrary input to a PHP script using mbstring conversion functions could cause the PHP interpreter to crash or, possibly, execute arbitrary code.
(CVE-2008-5557) A directory traversal flaw was found in PHP's ZipArchive::extractTo function. If PHP is used to extract a malicious ZIP archive, it could allow an attacker to write arbitrary files anywhere the PHP process has write permissions. (CVE-2008-5658) A buffer overflow flaw was found in PHP's imageloadfont function. If a PHP script allowed a remote attacker to load a carefully crafted font file, it could cause the PHP interpreter to crash or, possibly, execute arbitrary code. (CVE-2008-3658) A memory disclosure flaw was found in the PHP gd extension's imagerotate function. A remote attacker able to pass arbitrary values as the 'background color' argument of the function could, possibly, view portions of the PHP interpreter's memory. (CVE-2008-5498) A cross-site scripting flaw was found in a way PHP reported errors for invalid cookies. If the PHP interpreter had 'display_errors' enabled, a remote attacker able to set a specially crafted cookie on a victim's system could possibly inject arbitrary HTML into an error message generated by PHP.
(CVE-2008-5814) A flaw was found in the handling of the 'mbstring.func_overload' configuration setting. A value set for one virtual host, or in a user's .htaccess file, was incorrectly applied to other virtual hosts on the same server, causing the handling of multibyte character strings to not work correctly. (CVE-2009-0754) A flaw was found in PHP's json_decode function. A remote attacker could use this flaw to create a specially crafted string which could cause the PHP interpreter to crash while being decoded in a PHP script.
(CVE-2009-1271) A flaw was found in the use of the uw-imap library by the PHP 'imap' extension. This could cause the PHP interpreter to crash if the 'imap' extension was used to read specially crafted mail messages with long headers. (CVE-2008-2829) http://www.php.net/releases/5_2_7.php http://www.php.net/releases/5_2_8.php http://www.php.net/releases/5_2_9.php http://www.php.net/ChangeLog-5.php#5.2.9

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

It was discovered that php-json-ext, a JSON serialiser for PHP, is prone to a denial of service attack, when receiving a malformed string via the json_decode function.

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

The following four vulnerabilities have already been fixed in the stable (lenny) version of php5 prior to the release of lenny. This update now addresses them for etch (oldstable) as well :

  - CVE-2008-2107 / CVE-2008-2108     The GENERATE_SEED macro has several problems that make     predicting generated random numbers easier, facilitating     attacks against measures that use rand() or mt_rand() as     part of a protection.

  - CVE-2008-5557     A buffer overflow in the mbstring extension allows     attackers to execute arbitrary code via a crafted string     containing an HTML entity.

  - CVE-2008-5624     The page_uid and page_gid variables are not correctly     set, allowing use of some functionality intended to be     restricted to root.

  - CVE-2008-5658     Directory traversal vulnerability in the     ZipArchive::extractTo function allows attackers to write     arbitrary files via a ZIP file with a file whose name     contains .. (dot dot) sequences.

This update also addresses the following three vulnerabilities for both oldstable (etch) and stable (lenny) :

  - CVE-2008-5814     Cross-site scripting (XSS) vulnerability, when     display_errors is enabled, allows remote attackers to     inject arbitrary web script or HTML.

  - CVE-2009-0754     When running on Apache, PHP allows local users to modify     behavior of other sites hosted on the same web server by     modifying the mbstring.func_overload setting within     .htaccess, which causes this setting to be applied to     other virtual hosts on the same server. 

  - CVE-2009-1271     The JSON_parser function allows a denial of service     (segmentation fault) via a malformed string to the     json_decode API function.

Furthermore, two updates originally scheduled for the next point update for oldstable are included in the etch package :

  - Let PHP use the system timezone database instead of the     embedded timezone database which is out of date.
  - From the source tarball, the unused 'dbase' module has     been removed which contained licensing problems.

According to its banner, the version of PHP installed on the remote host is older than 5.2.9.  Such versions may be affected by several security issues :

  - Background color is not correctly validated with a non true     color image in function 'imagerotate()'. (CVE-2008-5498)

  - A denial of service condition can be triggered by trying to     extract zip files that contain files with relative paths     in file or directory names.

  - Function 'explode()' is affected by an unspecified     vulnerability.

  - It may be possible to trigger a segfault by passing a     specially crafted string to function 'json_decode()'.

  - Function 'xml_error_string()' is affected by a flaw     which results in messages being off by one.

It was discovered that PHP did not sanitize certain error messages when display_errors is enabled, 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-2008-5814)

It was discovered that PHP did not properly handle the mbstring.func_overload setting within .htaccess files when using virtual hosts. A virtual host administrator could use this flaw to cause settings to be applied to other virtual hosts on the same server. (CVE-2009-0754)

It was discovered that PHP did not properly handle certain malformed strings when being parsed by the json_decode function. A remote attacker could exploit this flaw and cause the PHP server to crash, resulting in a denial of service. This issue only affected Ubuntu 8.04 and 8.10. (CVE-2009-1271).

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.
